Justification (n.) is never final: nothing we do can be defended definitively, only by reference to some aim we must again simply accept.
Justification (n.) pictured as an infinite chain of reasons is like thinking a line has infinitely many parts because it can always be divided; the actual chain has a beginning.
Justification (n.) is sought where there is none: it would be meaningless to say I derive the word 'brown' from the colour-impression I receive.
Justification (n.) cannot be surveyed without surveying an expression's employment, not just some picture that clings to it.
Justification (n.) offered where none exists is the danger: we ought simply to have said, that's how we do it.
Justification (n.) is not needed for rightful use: to use a word without one is not to use it wrongfully.
Justification (n.) is what constitutes an assertion's sense.
Justification (n.) by a rule takes us no further, nor can it, into metalogic; do not justify what admits none.
