A book full of esoteric knowledge. White magic, green magic, blue magic, red magic and golden magic. Pythagoras, Leonardo da Vinci, Isaac Newton, and René Descartes are just a few examples of the most important scholars who believed in esotericism and practiced magical arts. Many of Shakespeare's works are delicately interwoven with magical beliefs. Sigmund Freud was notoriously superstitious, and Carl Gustav Jung made such a serious and profound study of magic that many of his detractors accused him of dabbling in mysticism.
