1. Reason

   Reason is the capacity for consciously making sense of things, applying logic, for establishing and verifying facts, and changing or justifying practices, institutions, and beliefs based on new or existing information. It is closely associated with such characteristically human activities as philosophy, science, language, mathematics, and art, and is normally considered to be a definitive characteristic of human nature. The concept of reason is sometimes referred to as rationality and sometimes as discursive reason, in opposition to intuitive reason. Reason or "reasoning" is associated with thinking, cognition, and intellect. Reason, like habit or intuition, is one of the ways by which thinking comes from one idea to a related idea. For example, it is the means by which rational beings understand themselves to think about cause and effect, truth and falsehood, and what is good or bad. In contrast to reason as an abstract noun, a reason is a consideration which explains or justifies some event, phenomenon or behaviour. The ways in which human beings reason through argument are the subject of inquiries in the field of logic. Reason is closely identified with the ability to self-consciously change beliefs, attitudes, traditions, and institutions, and therefore with the capacity for freedom and self-determination.

The Nuttall Encyclopedia(0.00 / 0 votes)Rate this definition:

1. Reason

   in philosophy is more than mere understanding or reasoning power; it is the constitutive and regulative soul of the universe assumed to live and breathe in the inner life or soul of man, as that develops itself in the creations of human genius working in accord with and revealing the deep purpose of the Maker.

2. Reason

   in German Vernunft, defined by Dr. Stirling "the faculty that unites and brings together, as against the understanding," in German Verstand, "the faculty that separates, and only in separation knows," and that is synthetic of the whole, whereof the latter is merely analytic of the parts, sundered from the whole, and without idea of the whole, the former being the faculty which construes the diversity of the universe into a unity or the one, whereas the latter dissolves the unity into diversity or the many.
