“Those who speak of progression but are afraid of change are self-repressed and therefore unable to reach any further than their eyes can already see.”
“He who cannot change the very fabric of his thought will never be able to change reality, and will never, therefore, make any progress.”
“But what can I do?' - I answer those who speak thus. - '... must I therefore not point out the evil which I clearly, unquestionably see?”
“The progress of human enlightenment can go no further than in picturing people not as vicious, but as mistaken.”
“People who want a cure, provided they can have it without pain, are like those who favour progress, provided they can have it without change.”
“Progress is impossible without change; and those who cannot change their minds cannot change anything.”
