Irrational

 

in the most general meaning, that which is beyond the bounds of reason; alogical or nonintellectual; incommensurable with rational thinking or even contradicting it. The irrational is generally contrasted with the rational. The irrational as something inaccessible to rational cognition and inexpressible in logical concepts is one of the basic reference points for a number of idealistic currents, jointly referred to as philosophical irrationalism (for example, intuitionism and voluntarism). In the religious world view the rational is viewed as prerational (spontaneous-chaotic, not shaped by the Logos), as distinguished from both the rational and suprarational (the mystical, given in revelation).

In the theory of knowledge of dialectical materialism the irrational is understood to be something not yet known but knowable in principle.
