What is secular learning?

I think the reason no one has answered the question, is simple, there are, like so many branches on a tree, more then one answer to what "Secular" is. But in the "Prima Facie" Secular, is Singular in nature, and Branches, are Branches, regardless of what Tree they Fall from. Secular Learning, would be by necessity of Secular itself, A Education Void of One Thing, and as most associate "Secular" as being Void of Religious Dogma, Secular Learning would become a Philosophy based on the principles of Science, and Physics, dealing with Cause and Effect. However, it could also be a Contradiction to what Secular has come to represent, in that it could end up being a Education Void of Science, where the Secular, or Singular Nature of the Learning, is Concerned with All Religious Dogma. This is my2centsworth, and if anyone opposes this explanation, let then show with clear arguments, as to why this explanation is flawed, and not simply that it's not correct, or you don't agree, or that my arguments are not clear to begin or end with.
