[Sir Francis Dashwood]

There is an objective basis for ethics, but it does not reside in the heavens.

Ethics, morality and all of those associated ideals, etc., etc., ad nausea, ...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.

[Senator Bedfellow]

Ethics, morality and all of those associated ideals, etc., etc., ad nausea, ...are rooted entirely in the presupposition some higher power defines what is correct for human behavior.

Funny position for a professed atheist to take. Is it your position that this presupposition is a "useful lie" then?
