When marrying, ask yourself this question: Do you believe that you will be able to converse well with this person into your old age? Everything else in marriage is transitory.
— Friedrich Nietzsche

Action is transitory, a step, a blow,The motion of a muscle, this way or that,'Tis done--And in the after-vacancy, We wonder at ourselves, like men betrayed.
William Wordsworth transitory quote

All things are only transitory.
— Johann Wolfgang von Goethe

All forms of beauty, like all possible phenomena, contain an element of the eternal and an element of the transitory -- of the absolute and of the particular. Absolute and eternal beauty does not exist, or rather it is only an abstraction creamed from the general surface of different beauties. The particular element in each manifestation comes from the emotions: and just as we have our own particular emotions, so we have our own beauty.
— Charles Baudelaire

For a transitory enchanted moment man must have held his breath in the presence of this continent, compelled into an aesthetic contemplation he neither understood nor desired, face to face for the last time in history with something commensurate to his capacity for wonder.
— transitory quotation by F. Scott Fitzgerald
