"...regrettable as it may seem to the idealist, the experience of
history provides little warrant for the belief that real progress,
and the freedom that makes progress possible, lies in unification.
For where unification has been able to establish unity of ideas
it has usually ended in uniformity, paralysing the growth of new ideas.
And where the unification has merely brought about an artificial or
imposed unity, its irksomeness has led through discord to disruption."
