Here is the argument and explanation;
- P1 IS = Reality, being, all-there-is.
P2 All-there-is comprises and includes 'ought_ness'.
C1 Thus 'ought' is "is"
C2 Therefore ought is derivable from "is'.
However, humans being self-aware is imbued with the awareness of duality for various reasons.
When Hume insisted 'there can be no ought from is' he was trapped in a world of duality but unable to realize the original and more fundamental truth of all-there-is as a monism.
The above entrapment is also suffered by the blinded and failed to realize the fundamental truth of reality. i.e. monism.
Note this 'monism' has nothing to do with any God at all but merely refer to what is really-real, i.e. all-there-is, being_ness.
Re the above argument is applicable to Morality [as defined generally];
P1 IS = Reality, being, all-there-is.
P2 All-there-is comprises and includes moral 'ought_ness'.
C1 Thus a moral 'ought' is "is"
C2 Therefore a moral-ought is derivable from "is'.
Agree, disagree??
