Organon

"Organon" and "Metaphysics" by Aristotle. I've found that the more I think in Aristotelian terms, the easier it is to design and model my systems.

My list: - Pirkei Avot, it's a section of the Mishnah (a part of the Talmud), it summarizes the jewish moral thought (well, not for the Karaites Jews, they did not believe in the Talmud), I was born in a Orthodox Jewish family so it was important on my beliefs, even though I am an Atheist now. - Organon, it's a compilation of Aristotle's logic works, they are the basis for the logical thought of the Western civilization, I think it's easier to read the originals than compendiums. - Philosophical Investigations, the second book of Wittgenstein, it's dense, and obscure to some extent, but it's really eye-opener, some ideas that influenced the last century are introduced there. - Proofs and Refutations, a posthumous work by Imre Lakatos, it defied much of my established view on how Mathematics works. - Thus Spoke Zarathustra, a powerful book, it's dense and you can only drag many conclusions from it when you read other works from Nietzsche, which lead to my next book.…
