Reddit mentions of On Creativity (Routledge Classics)

Perfect! You'll never look back once you go down this path.

Here's my favourite text of the year. It rambles near the end, but especially going through how we envisioned perspective before modern art it's just a fantastic little guide. You also get some basic background in theoretical physics from it, just as fascinating.

This one is more limited, but puts artistic developments of the early 20th century in perspective by drawing parallels between those and those of science. This and the above are very good if you still see art as painting pretty scenes.

Another by the same author, less involved with the parallels and more with the history.

This is a collection of essays, but they're brilliant. Nature of creativity and the creative process mostly.

These are the ones I know of offhand. Most of my library is a few hours away by car, but I'll be passing through there in a couple of weeks and can pick through titles if you'd like.

On Creativity, by David Bohm. It's sublime.
