Quote from ‘A Brief Intellectual Autobiography by Charles Sanders Peirce’


Metaphysics is still more special [compared to normative science], only considering the phenomenon in so far as it is a sign of what is real. [—] [U]nder the head of metaphysics will be included, not merely ontology, but also whatever philosophy can determine respecting causation, the freedom of the will, the connection of mind and matter, optimism or pessimism, immortality, theology, time and space, etc.

Peirce, 1983, pp. 71-72; MS [R] L107:19, 21
