A bit too deep for my muddy clarity this day.
But, as a not so well read non philosopher, I have always believed the answer to this question to be God, man and both.
I believe guidance came from the spiritual God yet man's influence is still profound in the making of law.
I also believe that man has a tendency to complicate everything beyond comprehension. These philosophers are a great example of that human failing.(with the exception of Jesus)
Smart answer. And good luck with the myopic poster who refuses to consider but one of those.
these philosophers . . . Some replies on thread have tipped us about the highly suspect grouping in the title and article. We have from Plato's presentation of Socrates that philosophy means a love of wisdom.
