[Sir Francis Dashwood]

Ethics are rooted entirely in the presupposition some higher power defines what is correct for human behavior.

Examine my statement for logic (categorical or propositional). It will test true as a syllogism or true if tested in a Venn diagram using Aristotle's logic.

Objectivists don't know how to use it.

"Examine my statement for logic (categorical or propositional). It will test true as a syllogism or true if tested in a Venn diagram using Aristotle's logic.

Your premise is incorrect.

'It' being what?
