rationalism
C1Formal, Academic
Definition
Meaning
The philosophical belief that reason and logical analysis are the primary sources of knowledge and truth, superior to sensory experience or religious doctrine.
In broader contexts, it can refer to any system of thought or behavior emphasizing logical, reasoned, and calculated approaches, often in contrast to emotion or tradition.
Linguistics
Semantic Notes
Primarily used in philosophy, theology, and intellectual history. It often carries a positive connotation of clarity and logic but can imply a criticism of ignoring emotion or empirical evidence.

Differences

Frequency
Low frequency in everyday speech in both varieties. Slightly higher relative frequency in US academic contexts due to 'rationalism vs. empiricism' debates in political science and economics.
