James Frederick Ferrier,
Introductory Lecture, Nov. 1861
(1883)

Why, you will ask, why may we not combine into one the two solutions just given, and thus obtain the most correct and the most tenable explanation? Why may we not say that our knowledge is due neither entirely to the mind itself, nor entirely to the action of external things, but that it is the joint result of both these constituents? ”
