Mike readily agreed that learnings came in various sizes, from little learnings that even a nestling could grok on up to great learnings which only an Old One could grok in perfect fullness.  But Jubal's attempt to draw a line between small learnings and great learnings so that "great learnings" would have the human meaning of "religious questions" was not successful, as some religious questions did not seem to Mike to be questions with any meaning to them (such as "Creation") and others seemed to him to be "little" questions, with obvious answers known even to nestlings - such as life after death.
