[dschiptsov]

Intuitions are insights (hints) from so-called ancient, non-verbal (pre-linguistic) instinctive "knowledge" or "genetic memory". It is not only the kind of knowledge of how birds "know" how to make nests or men know to run out of building when earthquake happen (without any prior training), but also intuitive knowledge about the nature of reality, properties of physical environment, which has been "trained" before any language, even before human species has been evolved (we share "pre-cortex" brain centers with our ancestors which were shaped by environment). This is where intuitions are coming from.

That is "instinct", a different concept from "intuition", thought overlapping in some aspect.
