- Speculative reason
Speculative reason or pure reason is theoretical (or
logical, deductive) thought (sometimes called theoretical reason), as opposed to practical (active, willing) thought. The distinction between the two goes at least as far back as the ancient Greekphilosophers, such as Platoand Aristotle, who distinguished between theory("theoria," or a wide, bird's eye view of a topic, or clear vision of its structure) and practice ("praxis"), as well as productive knowledge ("techne").
Speculative reason is contemplative, detached, and certain, whereas
practical reasonis engaged, involved, active, and dependent upon the specifics of the situation. Speculative reason provides the universal, necessary principles of logic, such as the principle of contradiction, which must apply everywhere, regardless of the specifics of the situation. Practical reason, on the other hand, is the power of the mind engaged in deciding what to do. It is also referred to as moral reason, because it involves action, decision, and particulars. Though many other thinkers have erected systems based on the distinction, two important later thinkers who have done so are Aquinas(who follows Aristotlein many respects) and Kant.
