Ancient Essentials

These are some of the titles that I think would be beneficial to the site.

The New Science by Giambattista Vico
900 Theses, Heptaplus, and Oration on the Dignity of Man by Pico Della Mirandola
The Elements of Euclid
The Lemmas of Archimedes
Summa Contra Gentiles of St. Thomas Aquinas
The Pistis Sophia
Prolegomena, and Critique of Pure Reason by Immanuel Kant
and anything by Kierkegaard

Some of these may be bound to too much red tape, but others I have seen in public domain e-text editions.
Thanks.:D
