Ellis,
... whether there really are different kinds of intuition depending on the research discipline.
I'd say "yes". For example, most people have a fairly good spacial perception but individuals appearing unable to imagine a two or three dimensional image exist. Isn't this a question of neuroscience rather than of mathematics? Neuroscience is barely established as a discipline. Without intending any offense, the subject has far to go before it can explain phenomena such as intuition. The question of how intuition works at present is perhaps analogous to the question of how planets move in the sky, asked in the year 1400. Celestial mechanics required roughly five centuries to "sort out". Intuition might take even longer. Best regards, ...
