Passions (philosophy) in the context of "Passions of the Soul"

A Treatise of Human Nature: Being an Attempt to Introduce the Experimental Method of Reasoning into Moral Subjects (1739–40) is a book by Scottish philosopher David Hume, considered by many to be Hume's most important work and one of the most influential works in the history of philosophy. The book has appeared in many editions since the death of the author in 1776.

The Treatise is a classic statement of philosophical empiricism, scepticism, and naturalism. In the introduction Hume presents the idea of placing all science and philosophy on a novel foundation: namely, an empirical investigation into human nature. Impressed by Isaac Newton's achievements in the physical sciences, Hume sought to introduce the same experimental method of reasoning into the study of human psychology, with the aim of discovering the "extent and force of human understanding". Against the philosophical rationalists, Hume argues that the passions, rather than reason, cause human behaviour. He introduces the famous problem of induction, arguing that inductive reasoning and our beliefs regarding cause and effect cannot be justified by reason; instead, our faith in induction and causation is caused by mental habit and custom. Hume defends a sentimentalist account of morality, arguing that ethics is based on sentiment and the passions rather than reason, and famously declaring that "reason is, and ought only to be the slave to the passions." Hume also offers a sceptical theory of personal identity and a compatibilist account of free will.

4 Maccabees, also called the Fourth Book of Maccabees and possibly originally known as On the Sovereignty of Reason, is a book written in Koine Greek, likely in the 1st or early 2nd century. It is a homily or philosophic discourse praising the supremacy of pious reason over passion. It is a work that combines Hellenistic Judaism with influence from Greek philosophy, particularly the school of Stoicism.

Fanaticism is a belief or behavior involving uncritical zeal or an obsessive enthusiasm. The political theorist Zachary R. Goldsmith provides a "cluster account" of the concept of fanaticism, identifying ten main attributes that, in various combinations, constitute it: messianism, inappropriate relationship to reason (irrationality), an embrace of abstraction, a desire for novelty, the pursuit of perfection, an opposition to limits, the embrace of violence, absolute certitude, excessive passion, and an attractiveness to intellectuals.
