In either case, both in the synthetic and the analytic process now described, we are dealing not with the _concrete_ but the _abstract_. The properties and relations of things, rather than things themselves, are the objects of our thoughts. Still they are the properties and relations primarily of _sensible objects_, and of these objects as _conceived_, and not as presented to sense. To distinguish this class of conceptions from those previously considered, and also from that presently to be noticed, we may designate this power of the mind as the _Discursive_ or _Reflective_ Power. Its results are notions of the _understanding_ rather than impressions of sense, or ideas of reason. _Conceptions not furnished by Sense._--_The Intuitive Power._--We have considered thus far those intellectual operations which fall within three leading departments of mental activity;--the Presentative, Representative, and Discursive Powers. These operations all have reference directly or indirectly to _sensible_ objects. The first regards them as _present_; the second represents them as _absent_; the third considers their properties and relations in the _abstract_. But the mind has also the faculty of forming ideas and conceptions not furnished by the senses. It departs from the sphere of sense, and deals with the _super_-sensible, with those primary ideas and first principles presupposed in all knowledge of the sensible. Such are the ideas of time, space, cause, the right, the beautiful. These are suggested by the objects of sense, but not directly derived from nor given by those objects. They are _ideas_ of _reason_, rather than notions of understanding. They are awakened in the mind on occasions of sensible perception, but not conveyed to the mind through the senses, as in perception, nor directly derived from the object as in the case of the representative and discursive powers. This faculty we may call the _Originative_ or _Intuitive_ Power, in distinction from those previously considered. _Summary of leading Divisions._--We have then four grand divisions of intellectual operations, under which the several specific faculties arrange themselves; viz., the Presentative, the Representative, the Discursive, and the Originative or Intuitive faculty. The first has to do with sensible objects, as present; the second has to do with the same class of objects as absent; the third deals with their abstract properties and relations; and the fourth has to do not with the sensible, in any form, but with the super-sensible. I believe the faculties of the intellect, in pure thinking, may all be reduced to those forms now specified, under these four leading divisions.
