sanity

Sanity refers to the soundness, rationality, and health of the human mind, as opposed to insanity. A person is sane if they are rational. In modern society, the term has become exclusively synonymous with compos mentis, in contrast with non compos mentis, or insanity, meaning troubled conscience. A sane mind is nowadays considered healthy both from its analytical - once called rational - and emotional aspects. According to the writer, G. K. Chesterton, sanity involves wholeness, whereas insanity implies narrowness and brokenness.
