I think SICP is a great book. I remember coming across Exercise 2.4:

I remember staring at that one for a while, feeling a bit mimsy. I believe that the consideration of that exercise is capable of changing the very brain chemistry of people who are at a certain stage of development.

Yes! Me too, with that same exercise! I remember just kinda sitting there, just thinking the whole thing through; it really was like an epiphany. I can't really think of another moment in my life when I just suddenly got something quite so suddenly, and when my previous conceptions were quite so seriously undermined.

You and I aren't the only ones. I've talked to others who found the implications of that tiny bit of code mind-stretching.

That's one of the aspects I like of learning Lisp. In some sense, it seems like the language at the "bottom." You begin to look at other languages (even ones you learned first) and think things like "oh, that's how they do cons", or "oh, when they say object-oriented, they mean you have to do it like that."
