Context

“This being so, Kant gave the title [Pg 86] objective to the intellectual factor, to the universal and necessary: and he was quite justified in so doing. Our sensations on the other hand are subjective; for sensations lack stability in their own nature, and are no less fleeting and evanescent than thought is permanent and self-subsisting. At the present day, the special line of distinction established by Kant between the subjective and objective is adopted by the phraseology of the educated world. Thus the criticism of a work of art ought, it is said, to be not subjective, but objective;” source
