- Does our intellect understand by abstracting the species from the phantasms?
- Are the intelligible species abstracted from the phantasms what our intellect understands, or that whereby it understands?
- Does our intellect naturally first understand the more universal?
- Can our intellect know many things at the same time?

- Can the intellect err?
- Can one intellect understand better than another?
- Does our intellect understand the indivisible before the divisible?
"It is because the contemporary alternatives seem so one-sided and are not more evidently solutions to the problems which Thomas faced, and partly solved, that we return to him and to the tradition of theology and philosophy in which his Summa Theologiae appears: theology as the science of the first principle and this as the total knowledge of reality in its unity." -- Wayne J. Hankey, God in Himself (Oxford University Press, 1987), p.159.
