In philosophy, non-rationalism is the rejection of the idea of rationality as a means of knowledge. Rationality means to discover something using logic, math, or empirical proof (statistics or data), so non-rationality involves using anything other than these (i.e.) using emotions to find knowledge). The main issue with non-rationalism is not how knowledge is discovered, since it is true that we can use other means to find it, but whether knowledge found by non-rational methods actually is knowledge in the true meaning of the term.
