Some simplification of complex abstract ideas is necessary, and I would assert that the appropriate degree is at least to the point where decision making and following action is possible. If nothing you say can be used to make an actual decision, then you are useless in all practical respects, outside of the entertainment value you provide those who tune to your channel.
With regard to morality, greatly simplifying, I would stipulate 4 moralities:
1) Be moral because God will punish you, and society will exile you.
2) Be moral because it is rational.
3) There is no such thing as morality.
4) Be moral because experience teaches this brings about both the most individual happiness, and the greatest overall social harmony and well being.
You do not have to justify the statement that “when I push button X, a horn toots”. It is a scientific claim, one which can be verified as often as anyone may care to. You don’t have to know WHY it works, merely that it does.
I will call this the Morality of Experience.
