“First impression only opens the door, but does not lock it.”
Conversation of 1930
Similar to Wittgenstein's written notes of the "Big Typescript" published in Philosophical Occasions 1912-1951 (1993) edited by James Carl Klagge and Alfred Nordmann, p. 175: Philosophical problems can be compared to locks on safes, which can be opened by dialing a certain word or number, so that no force can open the door until just this word has been hit upon, and once it is hit upon any child can open it.

“First impression only opens the door, but does not lock it.”
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.
