Uh, you don't seem to be making much sense - from your last two posts it appears that you agree that each of the following statements is correct:
(i) the ability to engage in precise reasoning is very important. (ii) the ability to memorize definitions is relatively unimportant. (iii) someone whose notion of a certain definition is as above will not be able to engage in precise reasoning.
Those three statements seem mutually inconsistent.
I imagine I'm missing something. Which part of what you've said am I misinterpreting?
