1. "Sound" in this context means "the premises are true and the conclusion follows". It doesn't make sense to say that premises are sound or unsound; ...

Why is Trump giving a blowjob to a microphone stand? Pretty weird.

They agreed to an initial deal but then Russia unilaterally changed the deal to include ridiculous terms that Ukraine was right to object.

That “diplomatic solution” was giving in to absurd Russian demands. All you really seem to be saying is that surrender is possible. And yes, it is, bu...

Not exactly. You were saying that A ? ¬A is necessarily false, which is saying that ¬A ? ¬A is necessarily false. But ¬A ? ¬A is true if ¬A is true, a...

A ? B means ¬A ? B. So A ? ¬A means ¬A ? ¬A. The argument in the OP is: ¬A ? ¬A A ? ¬A It's valid, but of course the premises cannot both be true. Nec...

All I can find about him is this: He doesn't seem to know what happened. But the above is consistent with what I posted earlier: Or, as explained abov...

It's a valid argument with two premises that cannot both be true and so is necessarily unsound.

You mean this?

Where are you getting this? I've read this and it says: This suggests that "the West blocked it" is just Putin's propaganda.

I'm a native speaker. I know what the words "swimmer", "solider", and "person" mean, and that they don't mean the same thing. For example, Michael Phe...

I don't get what's difficult to understand. "Human" and "solider" mean different things. "Human" and "swimmer" mean different things. "Human" and "per...

I was talking about being human, not about being a person. Do you understand that the words "human" and "person" mean different things? Do you underst...

In this context that the phase "being human" refers to some unambiguous set of necessary and sufficient conditions such that if some entity does not s...

You don't seem to understand what essentialism is if that it your response to that particular use of the term "essential".

See language games and family resemblances, e.g. Wittgensetin's question "what is a game?"

None, I don't want children. What is the purpose of these bizarre questions? They do not appear to have anything to do with whether or not membership ...

Allow her? I don't know why you're suggesting that I'm allowed to tell women what to do.

I wouldn't choose, it's got nothing to do with me.

No, I'm explicitly not an essentialist.

Single-celled humans are of the same moral worth as single-celled flies, i.e. worthless. Don't fabricate strawmen.

I have explicitly said several times that all single-celled organisms are of the same moral worth (specifically, worthless). Whereas you have continua...

So what about a species determines whether or not it is wrong to kill its innocent members?

So are you saying that it is only wrong kill an innocent organism if that organism is the same species as us? Are you saying that it wouldn't be wrong...

I did specify that it was "almost never the case" because I was specifically considering the fundamental particles of the Standard Model. That's preci...

Why does it matter what the single-celled organism develops into? Why is it acceptable to kill a single-celled organism that develops into an adult fl...

You assume wrong. The world is a mess of ever-changing matter doing ever-changing things. This matter gradually coalesces into various forms and behav...

It's like asking for the difference between a human and a language user. On Earth it happens to be the case that humans are the only language users, b...

First you were talking about being human, now you're talking about being a person. These are not the same thing (e.g. intelligent aliens would be non-...

That’s not essentialism. Essentialism is “the idea that things have an ‘essence’ or ‘form’ that defines their identity.” For some things this makes se...

Well, yes. I’m not a solipsist or an idealist. There is an independent material world, and two facts about that material world are that adults have he...

I don’t know what you mean by asking if we “must” see a difference. If we have working eyes then we will see a difference. If you cannot visually dete...

I don’t understand this either. If you can’t see a difference between these two photos then you should get your eyes checked.

Yes. Some say that one lone organ isn’t an organism, but that 5 of them (brain, heart, lungs, kidneys, and liver) working to keep each other alive are...

Essentialism is false. Whether we call zygotes, corpses, the brain dead. or babies born with anencephaly “human” is a choice, with no moral significan...

There are organisms, like me, that are self-aware, can feel pain, can want things, and so on. It is wrong to kill organisms like this. Zygotes aren't ...

"X is intelligent therefore X is human" is a non sequitur; something can be intelligent but not be human (e.g. an alien). It is not the case that I am...

No, I'm saying that (most) humans have a sufficient degree of consciousness/self-awareness/intelligence, and that it is wrong to kill things with a su...

We can, and do, kill non-human organisms, including single-celled organisms. You admit to killing flies. Is any of this wrong? If not, why are single-...

That's true of every single-celled organism. I want you to explain what makes single-celled humans special.

And why is that morally relevant?

That's where I disagree. I don't think the first question matters. I'm not an essentialist. There is no such thing as some necessary and sufficient se...

I don't believe in essentialism. If you want to use the term "human" to refer to any organism – even single-celled organisms – with such-and-such DNA ...

What human qualities does a zygote have? It is 46 molecules of DNA wrapped in proteins contained within cytoplasm and a cell wall. It strikes me that ...

It's not clear what you mean by this. A human zygote is a single-celled organism – 46 chromosomes surrounded by cytoplasm surrounded by a cell wall. A...

It's addressing his position. In his own words, "we know that an individual human lifecycle begins at conception, since it cannot begin anywhere else,...

Abortion isn't wrong because it's not wrong to kill single-celled organisms, regardless of what species biologists categorise these single-celled orga...

See my past posts. I ain't going to repeat them.
