Quote from ‘Forms of Consciousness [R]’


There are no other forms of consciousness except the three that have been mentioned, Feeling, Altersense, and Medisense. [—] Medisense is the consciousness of a thirdness, or medium between primisense and altersense, leading from the former to the latter. It is the consciousness of a process of bringing to mind. Feeling, or primisense, is the consciousness of firstness; altersense is consciousness of otherness or secondness; medisense is the consciousness of means or thirdness. Of primisense there is but one fundamental mode. Altersense has two modes, Sensation and Will. Medisense has three modes, Abstraction, Suggestion, Association.
