All of the laws of all of the worlds are *moral* laws at base.
Insight is the perception of those underlying laws, though they be occluded.
Intelligence is the comprehension of the moral substrate that underlies all potential and manifest phenomena and the understanding of how and why morality is manifest this way or that and/or is not.
Aptitude is the alacrity and celerity with which one puts the moral laws into practice in various forms. The greatness of any and all of the various aptitudes in any given person is in direct proportion to how well s/he serves morality and expresses it.
