On the pragmatist side we have only one edition of the universe, unfinished, growing in all sorts of places, especially in the places where thinking beings are at work.
On the rationalist side we have a universe in many editions, one real one, the infinite folio, or edition de luxe, eternally complete; and then the various finite editions, full of false readings, distorted and mutilated each in its own way. […]
And first let me say that it is impossible not to see a temperamental difference at work in the choice of sides. The rationalist mind, radically taken, is of a doctrinaire and authoritative complexion: the phrase ‘must be’ is ever on its lips. The belly-band of its universe must be tight. A radical pragmatist on the other hand is a happy-go-lucky anarchistic sort of creature. If he had to live in a tub like Diogenes he wouldn’t mind at all if the hoops were loose and the staves let in the sun.
– William James (Pragmatism, p. 600)
