It must be added here, as vital to the full comprehension of the genesis of matter, that not only every material object, like our example, the stone, is made of essential plurality of sense-effects, but that _every separate property_ of an object is also made of like plurality. No object, and no property of an object, is, or can be, single, unal, or, in other words, _anything_, until constructed so, in sense, by the "unconscious understanding" thereof--the synthetical unity of instinctive, automatic "apprehension." To realize this fact, it is only necessary to remember that every property of anything, say the hardness of a stone, is a compound relation between the impact of some ultimate non-ego on the sense of touch, and the peculiar nature of the sense itself: so the property of hardness must contain _essential diversity_, something from each of _two fundamental sources_. As Aristotle, from his ontological investigations, found that matter, if regarded as an absolute independence--an unrelated thing in itself--is _no thing_, but only chaotic indeterminateness--formless "potentiality"--so Kant, from his psychological inquiry--his dissection of phenomena as existent through perception--found the same truth in deeper significance. The _entire principle of unity_, Whether in a feeling, a thought, a material object, or the universe as a whole, _can only exist through the principle of mind_. Here is the very bottom of the discoveries of Kant, and the basis, also, of all things. Mind, then, in its lowest state, is what Kant, "to distinguish it from sensibility," entitled "unconscious understanding." There used to be an old saw in philosophy--still, indeed, at work--to the effect that "there is nothing in the mind that was not first in sense." Leibnitz, adding a piece to the saw, said: "Except mind itself." Leibnitz affirmed, that is, that sense always _contains_ mind--that mind is _in_ sense as a component of it, and that without mind there is no sense at all. What Leibnitz perceived and asserted, Kant _proved_ by "observation and induction"--by analyzing phenomena under the law of scientific idealism. Mind in sense--the mind of sense--is just _automatic animal awareness_, just "simple apprehension," undeveloped, and in the lowest animal life not to be developed, into "apperception," the _conscious_ stage of understanding, capable of forming a _concept_. Well, in the genesis of a stone, or any other material object, certain effects on sense are merged in the unit they compose, by reception into the "synthetical unity of apprehension." The stone is _created_ in this way. Its own objective unity--its wholeness, or "_form_" as a stone--is thus the derivation, the manufactured product, of _subjectivity as a cosmic element_, an element "_a priori_" to the existence of any possible phenomenon.
