My friend Phila sent along the following quote:
“If a man were to inquire of Nature the reason of her creative activity, and if she were willing to give ear and answer, she would say – ‘Ask me not, but understand in silence, even as I am silent and am not wont to speak.'”
– Plotinus, via the translator’s (F.L. Pogson’s) preface to Henri Bergson, Time and Free Will.
