“If thinking in the sense of intellection were the same as judging, for example, it would not be possible to think without judgment. We would not be able to accept a judgment without thinking because sometimes by mere intuition we accept the truth of a judgment, which in turn means that we do infer without intellection. What all this means is that thought is a necessary step in the process of knowing although in every knowledge acquired by the mind it may not be used because the preliminary ground has already been prepared by previous intellections. In fact, this is true of all faculties of knowledge; each faculty is a necessary element for the process as a whole, but not necessarily needed in every knowledge-acquisition process.”
