Epistemological psychology
The term episteme is related to the Greek word επιστήμη, which translates literally as "standing near or by that which causes" but is often simplified as "knowledge" or "science". By ignoring ego interests the core impetus or the essence of a deed, real or imagined, is recovered.
Epistemology
French philosophers then gave the term "épistémologie" a narrower meaning as philosophy of science. E.g., Émile Meyerson opened his "Identity and Reality", written in 1908, with the remark that the word 'is becoming current' as equivalent to 'the philosophy of the sciences.'
