Re: What could make morality objective?

No, you misunderstand validity. The 'in any situation' condition is absolutely critical: in any situation in which the premises are true, the conclusion is true. Sorry, but this is basic stuff. It's so basic and I "misunderstand validity" so much that I can trivially recognise your errors. https://...

Re: What could make morality objective?

This argument is invalid, because the conclusion doesn't follow from the premises. And the first premise happens to be false, but that's a separate issue. Stripped down, the claim is that Logik doesn't use these signs in a standard way. Yes. This is false. Deductive validity simply means that, in a...

Re: What could make morality objective?

1 If I say '2+2=5', and 'the sun orbits the earth', I'm demonstrably making mistakes, given the standard way we use those signs. This is an invalid argument. https://www.iep.utm.edu/val-snd/ In effect, an argument is valid if the truth of the premises logically guarantees the truth of the conclusio...

Re: What could make morality objective?

You are right to insist on moral criteria. Peter doesn't see the above as a problem... He draws a distinction between saying "murder is wrong" and saying "you are making a mistake". 1 If I say '2+2=5', and 'the sun orbits the earth', I'm demonstrably making mistakes, given the standard way we use t...

Re: What could make morality objective?

Correct. Hang on to that. And notice that we need to follow rules in order to assert that without rules you cannot assert anything. Notice the absence of a foundation for what we say beneath our linguistic practices. There is a foundation. Human cognition.The ability of the human mind to tell the d...

Re: What could make morality objective?

A rule has no truth-value, so it's neither true nor false. The rule has no truth-value. The rule is what establishes the criteria and mechanisms by which we determine truth-value. Without axiomatic rules you cannot assert anything! Correct. Hang on to that. And notice that we need to follow rules i...

Re: What could make morality objective?

We can try to justify our moral values and judgements by appealing to facts. We've been doing it since at least Aristotle. One argument is that, generally, humans need and want so-and-so, so it's morally right that they should have those things. This is the 'human nature' argument. Belinda challenge...

Re: What could make morality objective?

1 The identity rule is not that two things are the same, but that a thing is what it is: a=a; a rock is a rock. Meaningless tautology. Obviously a thing is what it is. But it can also be interpreted as a proposition. A is one rock rock. B is another rock A = B can be true. A = B can be false. A = A...

Re: What could make morality objective?

And as you are an adherent of classical logic, and therefore the identity rule. You have most definitely mistaken me for a classical logician. I reject the law of identity. To say "Two things are the same" is a contradiction in and of itself. How can TWO things be "the same". Can you be the same as...

Re: What could make morality objective?

A fact is a linguistic expression that correctly describes a feature of reality, given the way we use the signs involved. OK, we will come back to this in just a second to show you how much of decision theory you take for granted. Since you have been insisting on "logical connection" I shall oblige...

Re: What could make morality objective?

Why is that a moral truth and not a moral fact? I have no idea. You are still teaching me what "facts" are. Once you explain it better I may be able to identify a difference.

Re: What could make morality objective?

You claim there are such things as moral truths. :lol: :lol: :lol: :lol: I gave you a moral truth: "One should not kick Peter Holmes in the testicles". Why is that a moral truth and not a moral fact? Show one and why it's true - what makes it true. We're all waiting. What makes it true is the law o...

Re: What could make morality objective?

1 Please explain how to distinguish a moral truth from a moral fact. I don't know. You are the one who knows what facts are, yet you haven't been able to give me even a single example. 2 Please explain how to distinguish a moral truth from a moral falsehood. Examples of each would help. I can't. It...

Re: What could make morality objective?

No sign of a moral fact so far, but perhaps I've missed something. Pay attention. I am showing you moral truths, not moral facts. The way you are trying to get to "objective morality" doesn't work. I'm not trying to get to objective morality. I'm showing there's no such thing. Pay attention. 1 Plea...

Re: What could make morality objective?

1 A fact is an accurate description of a feature of reality. 2 If a moral assertion is a fact, it must be an accurate description of a feature of reality. 3 A moral objectivist must be able to show the feature of reality that a supposed moral fact supposedly describes. 4 If there are no such feature...
