|Metarationality - the mental landscape beyond the end of the tracks|
'Metarationality deals with valid phenomena which lie beyond the limits of discursive thought. Qualia are prime examples, and much meditational practice deals with the deliberate invocation of qualia.
Also, some types of meditation seek to go beyond conceptual thought in order to reach nonconceptual awareness.
Other metarational phenomena are those paradoxes that lie at, or just beyond, the limits of logical thought, and which have been investigated by Buddhist philosophers such a Nagarjuna.
According to Hume, the entire field of ethics may be metarational, since reasoned and logical arguments are incapable of going from an 'is' to an 'ought'. Ethics cannot be rationally derived either from knowledge based on logic and definitions, or from observation.
The difference between metarationality and irrationality, is that with metarationality you attempt to explore the landscape beyond the end of the tracks of logical thought, whereas with irrationality you come off the rails long before you reach the end of the line.

Buddhist philosophy is rational until it reaches the limits of logic, wherupon it goes metarational, whereas some religions are just plain irrational from the very start of the journey.
