Intellect, Intuition And Imagination

In Poul Anderson's Murder In Black Letter, the detective work is done not by the detective, Trygve Yamamura, but by his friend, Robert Kintyre, who:

consciously reasons about possible motives and suspects in a murder case;
but also feels or intuits that he already knows more than he has as yet consciously realized;
has perhaps three moments of sudden realization.

We have already seen that moments of realization are frequent experiences for Anderson's problem-solving characters. Yamamura is a Buddhist and a practitioner of judo who knows about Zen. Thinking about Yamamura and Kintyre, I suddenly made a link with my own three main interests from earlier in life:

philosophy - intellect;
spirituality - intuition;
science fiction - imagination.

Philosophy is analysis of concepts or thought about thought.
Zazen is "neither trying to think nor trying not to think; just sitting with no deliberate thought."
Hard sf = imagination + intellect.

I find that coherent and comprehensive.
