“Opening the fridge door, I found a rat eating the cheese. My dealings with rodents, particularly those tagged verminous, have been few, but generally the pattern has been one of man, the boss, the caretaker of creation, the namer, appearing and the lower orders hitting the road.”

Conversation of 1930, in Personal Recollections (1981) by Rush Rhees, Ch. 6
Variant: Philosophy is like trying to open a safe with a combination lock: each little adjustment of the dials seems to achieve nothing, only when everything is in place does the door open.

Context: All eyes are opened, or opening, to the rights of man. The general spread of the light of science has already laid open to every view the palpable truth, that the mass of mankind has not been born with saddles on their backs, nor a favored few booted and spurred, ready to ride them legitimately, by the grace of God. These are grounds of hope for others. For ourselves, let the annual return of this day forever refresh our recollections of these rights, and an undiminished devotion to them.
