Sir. W. Hamilton

Experiential

It is called empirical or experiential . . . because it is given to us by experience or observation, and not obtained as the result of inference or reasoning.

Immediate

The immediate knowledge of the past is therefore impossible.

Object

Object is a term for that about which the knowing subject is conversant; what the schoolmen have styled the “materia circa quam.”

Object, beside its proper signification, came to be abusively applied to denote motive, end, final cause . . . . This innovation was probably borrowed from the French.

Objective

Objective means that which belongs to, or proceeds from, the object known, and not from the subject knowing, and thus denotes what is real, in opposition to that which is ideal -- what exists in nature, in contrast to what exists merely in the thought of the individual.

Represent

The general capability of knowledge necessarily requires that, besides the power of evoking out of unconsciousness one portion of our retained knowledge in preference to another, we posses the faculty of representing in consciousness what is thus evoked . . . This representative Faculty is Imagination or Phantasy.
