Intuition (Anschanung) as used by Kant, is external or internal. External, sensuous intuition is identical with perception; internal intuition gives birth to ideas.
Matter and Form. “These two conceptions are at the foundation of all other reflection, being inseparably connected with every mode of exercising the understanding. By the former is implied that which can be determined in general; the second implies its determination, both in a transcendental sense, abstraction being made of any difference in that which is given, and of the mode in which it is determined. That which in the phenomenon corresponds to the sensation, I term its matter; but that which effects that the content of the phenomenon can be arranged under certain relations, I call its form.”—Kant, “Critique,” op. cit.
Objective. What is inherent or relative to an object, or not Myself, except in the case when I reflect on myself, in which case my states of mind are objective to my thoughts. In a popular sense objective means external, as contrasted with the subjective or internal.
Perception, if it relates only to the subject as a modification of its state, is a sensation. An objective perception is a cognition (Erkenntniss).
Phenomena (Erscheinungen). The undetermined object of an empirical intuition is called phenomenon.
Reason (pure; Germanicè, “Vernunft”). The source of ideas of moral feelings and of conceptions free from all elements taken up from experience.
Representation (Vorstellung). All the products of the mind are styled representations (except emotions and mere sensations) and the term is applied to the whole genus.
Representation with consciousness is perceptio.
Sensation. The capacity of receiving representations through the mode in which we are affected by objects is called sensibility. By means of sensibility objects are given to us, and it alone furnishes with intentions meaning sensuous intuitions. By the understanding they are thought, and from it arise conceptions.
Subjective. What has its source in and relation to the personality, to Myself, I, or the Ego; opposed to the objective, or what is inherent in and relative to the object. Not myself, except in the case when my states of mind are the object of my own reflection.
