[3] It should be understood that in the previous discussion so far as it
relates to Kant, I have taken him at his lowest terms—those of logical
self-consistency. So far as Kant does not succeed in freeing himself
from his original position—the existence of a formal, or apart, faculty
of thought—so far his emphasis of the _a priori_ in the sense already
attributed to him is inevitable. But that the _tendency_ of Kant is to
make the thought-relations _a priori_ simply in the sense of being fact’s
own anatomy and physiognomy I should not deny.
