Nothing too Small for so Small a Creature

I am petty; nothing petty is foreign to me. Or to my journal.

Richard Weaver, "Life Without Prejudice" in Life Without Prejudice and Other Essays, Chicago: Henry Regnery, 1965, p. 11:

Upon one occasion when Boswell confessed to Johnson that he feared some things he was entering in his journal were too small, the latter advised him that nothing is too small for so small a creature as man.
