"Poetry," said Auden, "might be defined as the clear expression of mixed feelings." Philosophy is the tenuous* expression of distinct thoughts.

*I tried a "intense", "terse" and "coherent", before hitting on this. The pangrammatical supplement of "clarity" is "intensity". The words tenet, tense, and tenuous share the same root, namely, "to stretch". So we can here capture the pangrammatical point, and also reproduce the "tension" (!) between "clear" and "mixed". Very satisfying exercise.
