Justification in Practical Reason
How do appeals to practical reason work?
Practical reason, roughly, is the concept of reason playing a role in action. It is thought to be quite different from theoretical reason because its aim is not truth, but proper conduct. This need not be moral conduct -- it can be prudence or self-interest. But in some way reason is still appealed to in deliberating on a proper course of action.
It would seem that appeals to emotion are pertinent. If we feel nothing then how could we make a decision? Surely the heart must play some sort of role, even if it be delimited to only include proper sorts of motivations (common injunctions here being against acting out of fear, but for acting out of compassion).
It would also seem that some kind of shared set of beliefs would be needed for appeals to work. Appeals, while emotional, would also have to be in part cognitive for them to be appeals, or for them to be counted as reason at all. And without shared beliefs there just wouldn't be anything cognitive to appeal to -- I have in mind here precepts, laws, commitments, or agreements.
Some might think that practical reason is entirely unworkable, a sort of over-reach born out of a desire to make everything subject to reason. But I think prudence is a good model to look at here -- we must, at times, make plans which requires us to bring to bear the powers of reason in deliberating on action. Also the intentional cultivation of good habits (or the cessation of bad ones) -- usually there is a reason we are doing so, and while it doesn't always work out it does some of the time.
I think there are probably limits to practical reasoning. I'd be interested in understanding the limitations of reason as it is applied to our practical lives. So rather than how does it work, I'd be asking when does practical reason work? When doesn't it work? And when should it and shouldn't it?

I think that the question is really too broad to be fairly answered. I'm more than happy to hear input, of course, but I'm also partially using this as a public scratch pad -- if something sparks, then great, but I'm sort of just thinking through things with the hope that input might be received.
Why the question is important: meta-philosophically I've come to believe two things. One, that philosophy and reason are inextricable. And two, that philosophy should address the needs of people. So philosophy is the pursuit of a good life through the path of reason. Or, in a more limited sense, philosophy is the pursuit of a good life when reason is called for.
While there are theoretical concerns in philosophy, as well, I think that from my side of things -- outside of academia -- that such concerns are not the main organizing principle of philosophy. I simply do not have the time necessary to deliberate such things (I also suspect that such debate is interminable and indeterminable, but I'd rather set that aside for now). But, regardless of the time allotted me, I and we all must do things. So in a sense this practical side of philosophy is more important merely by the fact that it is inescapable -- we all do things in the world. And insofar that truth matters to our doing we care about truth, but we can also ignore it to the extent that it does not impact upon our cares. But we cannot ignore waking up and having things to do. (I say "things to do" rather than "make choices" or some such formulation to avoid notions of choice, control, and will which are related but not of interest to me here.)
I phrase the question in terms of of the how of justification and when it's appropriate or working to avoid questions about what. I don't care what it is. I care how it works, how to phrase things more clearly, when reason should be used. Given my meta-philosophical beliefs these questions are similar to asking about the limits of philosophy, though I'd rather not go the meta-route. For me those answers are fixed at the moment. What is in flux, and uncertain, are my thoughts on reason.
All of this sounds very similar to the ethos that pragmatism propounded. For all intents and purposes, "practical reason" and "being pragmatic" could be used interchangeably.
Hope that helped.
I'm also drawing my inspiration from different thinkers, which is likely to bring up differences I think. So Aristotle and Kant make hey with this notion of practical reason vs. theoretical reason. And Epicurus sort of calls into question the importance of theoretical reason in his philosophy, as does Levinas, and places more importance on the practical, the ethical side of thinking. These are the thinkers that are on my mind in formulating things this way.

Interesting. I wonder what kind of eclectic philosophy you have compiled. Let us know so we may benefit too.
The slingshot argument, introduced to me on these forums (or the last?), persuaded me of the limitations of the correspondence theory of truth. I found what look to be lecture notes on it here which explains the argument pretty well step by step with examples.
Quoting Posty McPostface
Not necessarily. Though I don't mean to rule out any normative theory either. I'm more interested in the conditions under which an appeal to act thus and so, rather than otherwise, would work -- and the extent to which reason can influence action, and when it should or shouldn't.
Here I'm just trying to justify the distinction between theoretical and practical reason -- with theoretical reason appeals to emotion don't influence the truth of some proposition so it doesn't make a difference to justification. But in action emotion, pleasure, and so forth, do make a difference to how we actually act. They are important considerations in considering what it means to live the good life.
Quoting Posty McPostface
Heh. Thanks for the encouragement.
In order for an appeal to work it would seem that we would already have to consider the speaker as somehow someone worth listening to. Emotional appeals to shared precepts are not enough, as we can see there are many people who share a tradition but who simply do not listen to one another -- they view others in the light of someone who never says anything worth listening to. Consider, for instance, political parties in a democracy at odds with one another -- there comes a point where appeals are no longer being made. What use words are being put to is as tools of manipulation, as weapons to win, because there is an enemy to defeat. These are not appeals to reason, but strategies of war. All the same the two parties at least claim to have similar precepts.
So mere agreement is not enough. We need to hear another -- an Other? -- in order for an appeal to work. There is something about listening that must be incorporated.
I'd say that consensus is a process of justification rather than a defining feature of truth. Actually this is interesting because consensus can play a role in both justifying belief to build knowledge as well as in justifying collective action -- though would it still be proper collective action? Or is the nature of collective action such that it is merely necessary to build consensus in order for it to take place?
From what you wrote in the original post:
Quoting Moliere
I thought you and I were talking about the same thing. In what way is what you call "practical truth" different from what I call "political truth." I'm not talking about politics as in creating, enforcing, and judging laws, I'm talking about making group decisions about what to do next.
I just wouldn't call it truth. I'd say that we're aiming at proper action, rather than true actions. So there is what is true, and then there is what is good (unqualified, but not simpliciter -- just meaning I know that "good" can mean multiple things).
So theoretical reason is the use of reasoning in the pursuit of the goal of truth or knowledge. Whereas practical reason is the use of reason in the pursuit of the goal of the good or proper conduct (be it collective or otherwise).
Sure, me calling it political truth is probably a misnomer, but it's a purposeful one. I have written in a number of discussions that, to me, truth is really only a tool to help us achieve the real goal of philosophy, which is to figure out what we should do next.
I want to preserve this notion of theoretical thought. It makes more sense of much of philosophy -- rather than casting Plato's theory of the Forms in terms of a tool, it makes sense to say that Plato believed Truth to be a form which we could reach for. He seemed to also believe that knowing truth was enough to make good people -- in a way he collapses practical concerns into theoretical concerns. What the pragmatist does is the opposite -- truth is a tool to be put towards human ends, and nothing more. But this misses the meaning of truth, and also makes the practical concerns of life difficult to understand. (are we saying what we are saying about philosophy because it is a tool being used towards some end? Or are we implicitly assuming a theoretical notion of truth in setting things out thus and so?)
But with some kind of theoretical notion of truth as being somehow related to knowledge -- without a theory, it does seem we have a pre-theoretic understanding of truth, despite the problems with all theories of truth (including deflationary ones) -- it's easy to be able to say that what we are doing here, in producing knowledge, we can also use these abilities in the pursuit of other goals. One of which is the good life.
I don't want to commit myself to the notion that my normative claim on philosophy is the real goal of philosophy. Rather I think of it is a commitment on my part to what I think is interesting in philosophy for myself and possibly others like me. But it's wholly possible for someone to abandon that precept and engage in philosophy in a purely theoretical manner. In fact, many philosophers do exactly that. If they didn't share my precept, there would be no appeal I could make to them though. And while I think practical concerns are primary, in the sense that I want to intentionally make ethics my first philosophy, I can't deny that there are those with a thirst for truth and knowledge instead.
I have this image that comes to me when I deal with this issue. I don't intend this to be taken literally. It's just my way of thinking about it. It's an amoeba flowing around and moving away from something harmful or toward food based on chemical signals. There is an obviously very simple mechanism which tells the amoeba what to do. I see our nervous system as analogous to that. The whole thing is just a mechanism to tell us what to do next. Over billions of years, the mechanism has gotten a lot more complicated, but it's goal is still the same, to keep us alive by directing our behavior. Thought and consciousness are just manifestations of that mechanism. Knowledge and reason are just processes within that manifestation. Truth is just a possible feature of that process.
For me, looking at things through the lens of truth is misleading. To believe in truth you have to believe in the existence of objective reality, which I think is questionable. Actually, it's not a belief in truth or objective reality I reject, it's the belief that a view of reality including those concepts is somehow privileged over other ways of seeing things.
I am interested in this question. One interesting factor to me is the relation between ancient and modern. Aristotle considers an ethical education to involve inculcating the right 'habits'. Wittgenstein worries and worries over what it is to 'follow a rule'. It feels to me that 'habits' and 'rule-following' are similar if not identical phenomena. We arrive at rules/habits - we reflect on them, reason about them, perhaps try to change them - we have a new set of rules/habits. (Ari considers this ethical, though in a broader sense than the modern; Witt is unclear)
This is one approach towards practical reason or phronesis. It seems there is some process behind such analysis as encapsulated in the Aristotelian syllogism: there will be a series of steps from an initial set of presuppositions that make sense to us. We will have reasons-for. (Looked at in two ways: the post hoc reasoning, and the actual why-one-did-it)
The next and wierdest question is: How does a being make a decision? How is all this reasoning related to decision-making? Much writing on the subject just assumes some sort of relation. Yet much of the time it's like riding a bike: we practice over and over until we do an action without having to analyse how we're doing it. Even with intellectually complex decisions, how we act can boil down to such shortcuts, rules.
I've been reading about the tragic fire in a high-rise block, Grenfell Tower in London. Quite apart from the longer-term issues of how the building was refurbished, the decision-making on the night of the fire is a lesson in how we employ practical reasoning. Many people died by obeying fire officers' advice to stay in their flats, even turning back when they were escaping when so advised, turning back against their own self-wisdom to their deaths. The fire officers themselves were following their superiors' orders and their training. Deference to authority, and fidelity to rules for which the particular situation was inappropriate, got in the way of practical reasoning from first principles. We are highly intelligent animals but we are rule-followers, and the rule-following is part of what we think of as our intelligence.
I don't think your conclusion is correct. In a situation where I don't have experience or specific knowledge about the situation, it makes a lot of sense for me to listen to someone who is experienced and who, it's reasonable for me to assume, does have specific knowledge. People follow "their own self-wisdom" to their doom all the time. In this case, deference to authority wasn't inappropriate. Sometimes, even when you do things correctly, bad things happen.
I might have a broader notion of theoretical reasoning here that I'm not making clear -- because everything you say here, from my perspective, is purely theoretical. Concerns about objective reality, whether reason is rooted in our biological capacities, a world cast as a mechanism, and ways of perceiving reality that may be just as good as those concerned with spelling out the truth of things in a correspondent fashion where the word and world resonate with one another --- all of these are theoretical uses of reason. I say that in contrast to a practical reason which would actually tell me what is worth valuing, or give me some kind of consideration on how to act appropriately, or would orient persons to develop their characters in a good way.
In preserving notions of theoretical thought I don't mean to denigrate other ways of seeing things -- in fact I'd say that theoretical thought, broadly construed, would admit of a multitude of ways of seeing things. "Ways of seeing" seems to me to be a subset of theoretical thinking since we use such ways to perceive, believe, and think about the world.
I'd just say that it is true that there are other ways of seeing things. ;)

I agree that the relation between the ancient and the modern is really interesting. And, as my thinking goes anyway, I have a tendency to synthesize between the two. For one it seems to me futile to propose ancient ethical philosophy as a serious contender if we take it to the letter -- those were different times.
For two, we have to be able to speak to people. And modern thought on ethics is necessary to proceed in this manner.
I had never thought about the relationship between Witti's rule-following and Aristotle's habits. I think you're on to something there. Especially through habituation -- we don't come to question a habit without some kind of force. And with rule-following we simply follow the rule as a necessary part of playing the game -- to question the rule is similar to questioning a habit. (though with Witti we get no guidance on the ethical either).
Quoting mcdoodle
I'd be interested in hearing more about this series of steps. I can kind of see it with respect to the syllogism, and it certainly fits Aristotle's patterns of thought, but I'm wondering how you relate that back to habituation and rule-following. Like, there's a series of habits which build good character and develops phronesis?
Quoting mcdoodle
Definitely. For now I think it might help to just look at how we might change our decisions rather than trying to find a base for making any decision. At least our acts are always in play, and we can see that we do, in fact, change course -- and sometimes that change of course is because of reason. "Because" not in a causal sense here. The causal mechanism, I think, is a purely theoretic way of coming to understanding human action. So we get Freud's unconscious, and a dollop of post-hoc rationalizations after the fact. But in what way is that even useful to thinking through a decision, or deliberating on the right way to become, or making a decision in the face of an event that calls into question a previous habit?
None. It would almost be laughable if someone were to tell me that they did something because they had to resolve some unconscious drive. It would be like they stepped outside of themselves and pictured themselves as a sort of machine, realizing they only had one lever and pulled it. Like, who thinks like that? And, if so, how does it actually help in thinking through our actions?
I think you're right to say that it's like riding a bike, and that there are certainly "short cuts" involved -- I don't think that syllogistic reasoning or reflective reasoning plays the primary role in our daily actions. I think habit has a lot to say here (though, side note: I am interested in habit, too. What lies under the hood of habit? And what does the explanation of habit actually explain?). Only that it plays some role some of the time (and, possibly, could even be made to play more of a role, though I don't know if that's even desirable)
Quoting mcdoodle
Sometimes I think the rule-following bit is a bit more a convenience of the world we live in and a product of our educational systems. It's easier to govern large swathes of people who are accustomed to hierarchy and authority.
That's a terribly sad story, though. Instead of trusting what was right in front of their face they trusted the words of authority. That's kind of crazy.
The tragedy of the case is though that many of the tenants fleeing had more knowledge about the fire than the fire officers who advised them. But they valued their knowledge less than they valued the rightness of authority. I'm not offering an ethical judgment. It's tragic. No-one is to blame, as between tenant and fire-officer.
I only meant the steps in some sort of process of inference.
I do think that in say bike-riding we learn a series of steps, until by repetition we don't even think about the steps, we 'just do it'. So knowing-how is built up from knowing-why. Our reasoning is built into things we have learnt to do automatically, like making tea or feeding the cat. It's hidden in familiar acts.
Quoting Moliere
Just to use language, though, as an example, is an example of rule-following. Our carers teach us over and over again until we get it. Then we become so habituated to it that we forget we once learnt to follow rules to do all this saying and hearing. We are rule-following animals. The authoritarians use this fact about us to inculcate their ways into us. But left to myself I learn, say, a route to a place, and then I take that same route over and over, sometimes in defiance of people who tell me about rationally better routes: I know my route, I trust it, I'm safe along it.
I think you have the better way of putting it. Good point with language-learning, something which is certainly prior to authoritarian structures.
I think this notion of safety and trust is close to habit. So we might change our route if we care about something more than our familiar and safe and trustworthy patterns have thus far proven comfortable -- perhaps there's a new shop along another route, or we find the standard route becoming congested with traffic. In a sense this is perfectly rational -- I have in mind, if someone were to tell you a shorter way of getting somewhere, that while if you cared about saving time then it would make sense to try it, but given that you care about familiarity you're being more rational by following the same route than by adhering to some other standard that falls outside of your care.
Quoting mcdoodle
Got it.
Reason is "baked in", so to speak. There's a series of events or lessons or steps that are reflected upon, but then through repetition the awareness of those steps sinks into the body and stops being something
reflected upon.
This is interesting too -- rather than looking at reason as a series of rules or norms for thinking, this seems to cast reasoning as whatever takes place in the process of learning, and the motivation (know-why) for such learning to take place.
I like the bike example. You can spend time watching people ride a bike, you can pick up a book and read all about how a bike works, and you can touch and feel a bike but until you try, and you learn how to ride a bike you cannot say you know what it means to ride a bike.
Similar to the Mary's Room thought experiment. Mary can learn all about the color red while in her white room, but until she gets out in real world an experiences the color red, she can't be said to know the color red.
Quoting Moliere
It feels as if the premisses count a lot, but only given that we have some kind of mutual agreement that syllogism-style steps are reasonable.
If the steps are accepted, what *matters* to the person appealed to has to be found and invoked, otherwise the superficially rational argument falls on stony ground. (As someone who has spent many hours as a Green candidate or advocate failing to persuade voters of the merits of my case, I believe I have some experience of this stony ground) We have to find at least a mutually-common premiss to get anywhere. This zone is where many rational-seeming people trying to appeal to what they regard as practical reason get stuck. They get frustrated or angry that others don't get their argument. They are apt to think others are being 'irrational' when it may be that they are coming at it from different presuppositions.
Phronetic explanations seem to need to satisfy both explainer and the explained-to. I'm interested in medical diagnosis in this context. Doctors/nurses need a conclusion as much as a patient does. Sometimes then a the invocation of a so-called 'syndrome', or some other way of just summarising symptoms, masquerades as a diagnosis when in honesty it falls short. To name symptoms well is an important step, but it isn't a diagnosis that can lead to a prognosis. It is however somehow satisfying in lieu of the meaningful.
Many decades ago I was between homes and only had an old black-and-white tv set on which to watch snooker which has multi-coloured balls. I came to learn which was a red ball (there are a lot of them in snooker) but I didn't through the telly experience redness. I am never quite sure I accept Jackson's notion that you can 'learn all about the colour red' without experiencing redness. But I quite take your comparison.
Heh. That strikes a chord with me. I've experienced the stony ground before, too.
This kind of reminds me of the parable of the sower.
That's a good point. One of the things in the back of my mind while reading your reply was the thought of organizing. There's a school of organizing which treats the organizer as a kind of enlightened individual who knows what people want better than they do. What's more is that, doing enough organizing, sometimes it's even true that you know what people want more than what they do given certain practical circumstances that the people you organize are usually unaware of.
So you can easily convince yourself of your enlightened cred.
But this sort of relationship usually omits the organizer from being satisfied by some explanation. The organizer acts in a professional capacity to serve the people explicitly and only. And explanations no longer really act like appeals at that stage -- they are what people want to hear, and they move them to the best outcome given the circumstances, but there is a hard asymmetry between the organizer and the organized. Similar to the patient and the analyst, actually. (not sure about doctor, though. Maybe at one point, but the medical field seems to have incorporated patient input into their practice, from my cursory glance)
That is, there are no explanations or appeals, they are tools to move people thus and so.
But having that double requirement sort of gives a golden mean between two points -- on the one hand, the problem of rational people that you highlight. And then on the other hand, the problem of assymetric knowledge or status. Both, in a sense, are a deficiency in being able to listen, just from different reasons -- one is too wrapped up in their own reasoning, and the other is too wrapped up in an "objective" theoretical construct of the Other's reasoning. But the mean would have us listen to an Other, and find common ground in order to build what could reasonably count as rational phronetic explanations or reasons.
Taking the medical "analogy" to the next step, eh? :D
That's cool. Maybe I should delve more deeply into that area.
In my mind I'm sort of trying to work out what it would be to make an appeal as equals, though clearly there are always going to be asymmetries of some sort too just through natural ability.
Emotional attachment or motivation (know-why)
Shared beliefs or commitments to which appeals can be made or made from.
The belief that a speaker is someone who is worth listening to.
The explanation must satisfy both the spoken-to and the speaker.
Experience in the area under consideration (like riding a bike -- you wouldin't listen to the Mary of bike-riding, studious though she is, you would be more likely to listen to the person who has ridden a bike quite often)
The way I see it ''practical'' reasoning is a slave to our nature. Reason applied to satisfy our desires. ''Practical'' reason is like money - a means to achieve ends. The rules of logic apply though and apart from some fallacies logic is used to achieve goals whatever they may be.
''Philosophical'' reasoning has one more responsibility - that of finding good desires to apply our logic to.
I view reasoning as an activity that humans can do. So rather than looking at it as a tool, it's really more of a power -- we don't use reason like we use a hammer. We use reason like we use seeing -- it can be put to multiple functions, some of which aren't exactly bound to desire in an ends-means relationship. Rather, we are motivated to do something -- reasoning comes out of or flows forth from emotion or motivation. It is something of an art, really. It can be taught and developed, as one develops one's ability to paint or act.
So the when, from my perspective at least, comes about when reason ceases to be the best art to practice. Sometimes we should be poets, and sometimes we should be reasoners. But when is it best to reason? And when does it get in the way?
(There's something of the imagination at work in this.)
For a justification to work we would have to have some kind of familiarity with the art of reasoning, to trust that reasoning can help, to be able to sort good reasons from bad ones, and have some sort of practice in making judgments of this sort.
Never say never or always. It's a known fact that nothing is applicable for all cases - there usually is an exception. For instance I find reason inappropriate for morality. Proof? People call the good ''naive''. In other words it's foolish to be good in the world as it turns now. Strangely, it's reason that makes us see just that. Confusing!
Philosophy pushes the boundaries of sense. With new philosophy new concepts or ways of thinking are explored. If it were always bound by teleology then philosophy would almost just be the engineering of the mind, trying to make better inferences, clearer explications, or more certain truths.
Simultaneously if philosophy were not bound to reason then it begins to look too much like other activities -- like writing poetry or prose, politics, proselytizing, self expression, or simply writing a journal. It loses what has been an enduring quality of philosophical writing -- appeals that, in principle, are evaluable on the basis that they are made rationally or for reason to consider.
Or, in the case of medical philosophies, reason was being put to use in the service of said medical desires or needs.
So I'm tempted to call philosophy proper the art of reasoning, where the teleological structure of reason is temporarily suspended and concepts are created out of the principles of reasoning itself. So we can follow an argument or make an argument or some such, just as a painter can paint a representation of a street or a person. It's still art to do so. But the suspension of goals or representation (for reason and painting, respectively) creates a kind of play with the principles themselves -- hence the art of reason, or the art of painting. There's even a play in just putting the principles to use, in setting up a picture just so, or coming up with a story or example that fits just right to some general principle or argument being made.
but the key thing I'm trying to resolve here is the claim that reason is teleologically structured, philosophy is entirely useless (but valuable), and philosophy is inextricable from reason.
Disinterest applies to art as well as it does to reason. The beauty in art does not depend on any pleasure referenced by the work. Beauty lies in the extrinsic relationship between form and matter in the work, which drive our intrinsic judgement of taste. Beauty lies in the play between form and matter, but this play of the senses is non conceptual. It only becomes conceptual because we can universalize (idealization) the particular thereby expanding our conception of what is beautiful.
The formal principles (form) of action are either hypothetical or categorical imperatives, where a hypothetical imperative is instrumental in achieving a useful end, a categorical imperative formalizes the sense of duty which we intend/legislate as a reasonable principle (matter) of our action to serve as if ( Play) a universal law of reason. Kant's moral philosophy as in art also universalizes the particular. He based the motivation for our actions in our sense of duty ( as the product of the absolute freedom of our will which must be assumed for morality to exist) in which reason also must be disinterested in its moral pursuit.
I think trying to frame it in terms of how is better just because I agree that it is very hard to be clear on what is involved. But I think it's a little easier to say how -- like the elements and principles of visual art. They don't really specify what art is, they're just general guidelines for how to think about art in order to make art. And true mastery of an art often involves the intentional breaking of those guidelines. But that only comes with thousands of hours of practice.
So maybe the conditions I listed are a bit too clinical -- as seen from the outside, based upon examples of practical reasoning, rather than ways of thinking through a practical problem.
While I think that Kant is closer to Hume than traditional readings tend to render him, I will say that he doesn't allow for many motivations inside of his account of practical reason. He also is primarily interested in practical reason in its moral sense, and I don't think that's quite right. Insofar as we are deliberating about action then I'd say that practical reason is being applied or appealed to. But a lot of our actions are not strictly moral, especially in a deontological sense. Plus it seems to me that we can be motivated by more than respect even within moral deliberation, and especially in ethical deliberation.
Disinterest, as I see it, would apply in cases where advice is being given by some trusted person. So a priest, a counselor, a friend, a mentor, or something along those lines.
But then we can also use reason to our own benefit. While there is something good to be said about not being caught up by certain passions, we are passionate beings. And reasoning about our own well-being is anything but disinterested, even in the specific Kantian sense.
There is something important learned in thinking through a character or role -- you have to develop motivations which may not be your own, you have to think from the perspective of a total other while being able to relate to that other just enough to make it come to life, and you have to do more than just think through said relation -- you have to embody this other person, and in a sense -- if only temporarily and within the confines of an art -- become them. By playing tragic roles, comedic roles, and things in-between (even two dimensional roles, at times) you get a feel for the human being in practice without the total effects on your actual life.
While there is more to consider in play acting than just these considerations (such as making an entertaining play, or standing in a way that you can be seen), there is something about others that comes to light in taking on them as if they were yourself, and not just in fantasy but in a way that it is at least believable in a play acting setting.
I also don't want to overemphasize the art in terms of practical reason. We can get lost in fantasy. But such is also the case even when dealing with real problems in our life. I think acting just helps in being able to step outside yourself, just a little bit, and even come to understand yourself a little better as you make comparisons, distinctions, and relations to something that is not ourself.
I like that. To some degree (perhaps a significant degree) emotions do tell us what matters to us. And of course what matters to us contributes to deciding which issues get our attention.
