I'm not a fan of fiction books.

Fiction relies on made-up characters, plots, and metaphors to explore aspects of reality and human nature.

I find it much more fun to learn the core ideas presented directly.

This is a play on the meanings of words.nnScience and philosophy are both conjectural.nnThe 'made up' in the OP referred to the additional baggage that surrounds the core ideas.nnSo we have:nnnon-fiction → 'made-up' guesses about realitynnfiction → 'made-up' guesses about reality with additional 'made-up' baggage
