The Rules for the Direction of the Mind is an unfinished treatise on method by René Descartes, written around 1628 but published only after his death, in 1701. It sets out a series of rules, each followed by explanation. The first states that the end of studies should be to direct the mind to make solid and true judgements about everything that presents itself. Descartes argues that the sciences are one, being all human wisdom, and should not be studied separately as the arts are. Later rules treat intuition and deduction, the order of inquiry, enumeration, and the use of imagination and the senses; the sample explains the role of the brain, the imagination and the nerves in perception and movement.
The Regulae is the earliest of Descartes’s philosophical works and shows the development of his method before the Discourse of 1637. Its ideal of a universal science modelled on mathematics, and its emphasis on clear and distinct intuition and orderly deduction, became central to his philosophy. The work circulated in manuscript before its publication, influenced the Port-Royal Logic, and was read with interest by Leibniz, who owned a copy.
