Yes, but I was accused, without supporting argument for the accusation, that I did not understand it. :smile: — Janus
Yes, quite right - I could not make head nor tail of what you represented the Euthyphro to be. I then very kindly laid out what I take the Euthyphro to be and asked if you agreed, but you said nothing.
So here is the relevant portion of that post again, copied and pasted.
Tell you what, to move things along I'll suggest what the supposed problem may be, and you can just confirm that it is as I say it is.
The problem is that if moral values are the values of a subject, then they can change over time. What's morally valuable at one time, may not be at another. For after all, we know from our own case that what we value can alter. I may value sunshine at one time, but not at another. Tastes can and do change.
And thus, though - for example - pain seems to be in generally something that is morally bad, nothing stops it from being the case that in the future pain might be morally good. For the subject-whose-valuings-constitute-moral-values - let's call her Trisha for convenience and so that you don't keep calling her God - may value us suffering in the future even though she currently seems to disvalue it.
Why is that a problem? Well, because, as most contemporary moral philosophers agree, moral truths appear to be necessary truths. Just as it is necessarily true that the conclusion of this argument will be true if the premises are -
1. If P, then Q
2. Not Q
3. Therefore not P
likewise it is necessarily true that sadism is morally bad, when it is bad.
The above argument does not just happen to be valid at the moment. It is always and everywhere valid. Its validity does not alter. It does not have a best-before date.
Likewise for substantial moral truths. Such truths may be very complex and sometimes hard to discern - like the answers to complex sums - but whatever they are, they are necessary truths.
So, expressed as an argument, the problem the Euthyphro draws attention to is this:
1. If moral values are the values of a subject, then what is morally valuable will be contingent, not necessary.
2. Moral values are necessary, not contingent
3. Therefore, moral values are not the values of a subject
Fair enough?
