My favorite Oliver Wendell Holmes quote, by far:

Wright, a nearly forgotten philosopher of real merit, taught me when young that
I must not say necessary about the universe, that we don’t know
whether anything is necessary or not. I believe that we can bet on
the behavior of the universe in its contact with us. So I describe myself as a betabilitarian.

You may recall that Kant’s atypically good on betting, too.
