The Book of HealingThe Book of Healing (کتاب الشفاء; Sufficientia; also known as ) is a scientific and philosophical encyclopedia written by Abu Ali ibn Sīna (aka Avicenna) from medieval Persia, near Bukhara in Maverounnahr. He most likely began to compose the book in 1014, completed it around 1020, and published it in 1027.

Existence of GodThe existence of God (or more generally, the existence of deities) is a subject of debate in theology, philosophy of religion and popular culture. A wide variety of arguments for and against the existence of God or deities can be categorized as logical, empirical, metaphysical, subjective or scientific.

XenophanesXenophanes of Colophon (zəˈnɒfəniːz ; Ξενοφάνης ὁ Κολοφώνιος ksenophánɛːs ho kolophɔ̌ːnios; c. 570 – c. 478 BC) was a Greek philosopher, theologian, poet, and critic of Homer from Ionia who travelled throughout the Greek-speaking world in early Classical Antiquity.

Meditations on First PhilosophyMeditations on First Philosophy, in which the existence of God and the immortality of the soul are demonstrated (Meditationes de Prima Philosophia, in qua Dei existentia et animæ immortalitas demonstratur) is a philosophical treatise by René Descartes first published in Latin in 1641. The French translation (by the Duke of Luynes with Descartes' supervision) was published in 1647 as Méditations Métaphysiques.
