Note (return) — Chapter VII

"The relativity of human knowledge," like most other phrases into which the word "relative" enters, is vague, and admits of a variety of meanings. If by this phrase is meant "that we can not know objects except as related to our faculties, or as our faculties are related to them," we accept the statement, but regard it as a mere truism leading to no consequences, and hardly worth stating in words. It is simply another way of saying that, in order to an object's being known, it must come within the range of our intellectual vision, and that we can only know as much as we are capable of knowing. Or, if by this phrase is meant "that we can only know things by and through the phenomena they present," we admit this also, for we can no more know substances apart from their properties, than we can know qualities apart from the substances in which they inhere. Substances can be known only in and through their phenomena. Take away the properties, and the thing has no longer any existence. Eliminate extension, form, density, etc., from matter, and what have you left? "The thing in itself," apart from its qualities, is nothing. Or, again, if by the relativity of knowledge is meant "that all consciousness, all thought are relative," we accept this statement also. To conceive, to reflect, to know, is to deal with difference and relation; the relation of subject and object; the relation of objects among themselves; the relation of phenomena to reality, of becoming to being. The reason of man is unquestionably correlated to that which is beyond phenomena; it is able to apprehend the necessary relation between phenomena and being, extension and space, succession and time, event and cause, the finite and the infinite. We may thus admit the relative character of human thought, and at the same time deny that it is an ontological disqualification. 305
