My advice to you is not to inquire why or whither, but just enjoy your ice cream while it’s on your plate—that’s my philosophy.

Framed as practical “advice,” the line urges a turn away from anxious metaphysical questioning (“why or whither”) toward attentive enjoyment of what is immediately given. The homely image of ice cream emphasizes life’s small, perishable pleasures: they melt if you postpone them for abstract speculation. At the same time, the phrasing doesn’t necessarily reject meaning-seeking altogether; it suggests a hierarchy—live first, savor the present, and don’t let ultimate questions paralyze ordinary happiness. The tone is wry and conversational, characteristic of Wilder’s ability to compress philosophical counsel into everyday speech.
