Medisense

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.

The removal of sensation from the department of cognition, or Knowledge, leaves nothing remaining in that department except what are called Mediate Cognitions, that is, Knowledges through some third idea or process different from either the Knowing self or the Known object. For the sake of giving this Mediate Cognition, or rather the peculiar kind of element of consciousness it involves a single name, I will call it medisense, that is, the consciousness of a middle term, or process, by which something not-self is set up over against the consciousness. All consciousness of a process belongs to this medisense.
