> Secularism is a recent thing.
Sokrates and Buddha would like a word.
Socrates and Buddha were 2,500 years ago and I don’t think I’d describe them as being secularists. Secularism is something that came out of the Enlightenment, in the West at least. It is absolutely a recent thing for the purposes of the discussion.
Reincarnation, the soul, karma, etc aren't exactly compatible with materialistic secularism.
