Could you provide a working example of a “metaphysical leap of faith” upon which a series of values would be based by a secular humanist state ?
Sure -- it's too easy, because basically everything that is not rooted in empiricism is a sort of value judgment, and I think that you could even argue that empiricism itself brings with it its own value judgment.
So, even if we say something like
men and women are equal, what most people in the world view as highly agreeable and think of as a sort of basis for many of our laws based on gender equality, it is still very much just a leap of faith. There is nothing in the natural world that would suggest
men are equal, let alone
two distinct genders with different physical characteristics and even different tendencies in their cognitive lives are equal.
You would be hard pressed to even find evidence for a statement that
men with the same father are equal.
But, it is treated as a sacred principle, and it is just commonly accepted conventions enshrined in our Western liberal democracies, in spite of the fact that there is nothing in the natural world to suggest it is true.
These things are all metaphysical leaps of faith that our secular humanist societies have come to.
