The different branches of philosophy are:Well, okay then. Make the case that epistemology only concerns itself with what is and not at all with what ought to be.
- metaphysics - or what exists
- epistemology - or how do we know it
- ethics - or how should we behave.
There is also - aesthetics - or what is beautiful or ugly. But that is totally irrelevant. Beauty is in the eyes of the beholder.
Because “IS” statements deal with objective reality, while “OUGHT” statements deal with BOTH the reality and our preferred actions toward the reality. And your preference is likely o be different from other people’s preference.Why can’t ethics ( OUGHT statements) be just epistemologically grounded as IS statements?
As they say: “asserted without evidence, discarded without evidence.”My claim would be that we can be as epistemologically certain about OUGHT claims as we can be about IS claims. Prove me wrong.
You would be wrong. The law of non-contradiction is essential to separate “true” and “false” statements. Without it there cannot be a conversation. Actually, even the negation of this principle would need its acceptance. And the “principle of sufficient reason” is simply incorrect. Any hierarchical system needs a starting point, which is not subject to further substantiation. Axioms cannot be “proven” - they don’t need any “sufficient” reason.I would have no hesitation stating that the logical law of non-contradiction or the principle of sufficient reason are no more self-evident than, We ought not murder or torture innocent human beings.
And as for “we should not murder or torture innocent human beings”… the psychopath will counter it with: “Why not? It is major fun!” and what logical arguments can you present that will be persuasive to this psychopath?
