Every thinker puts some portion of an apparently stable world in peril and no one can wholly predict what will emerge in its place.

Experience and Nature (1925), Ch. VI: Nature, Mind and the SubjectJohn Dewey
Prediction of the future is possible only in systems that have stable parameters like celestial mechanics. The only reason why prediction is so successful in celestial mechanics is that the evolution of the solar system has ground to a halt in what is essentially a dynamic equilibrium with stable parameters. Evolutionary systems, however, by their very nature have unstable parameters. They are disequilibrium systems and in such systems our power of prediction, though not zero, is very limited because of the unpredictability of the parameters themselves. If, of course, it were possible to predict the change in the parameters, then there would be other parameters which were unchanged, but the search for ultimately stable parameters in evolutionary systems is futile, for they probably do not exist... Social systems have Heisenberg principles all over the place, for we cannot predict the future without changing it.

Though widely attributed in these forms, they are apparently paraphrased from the quote "the world is in greater peril from those who tolerate or encourage evil than from those who actually commit it" from Conversations with Casals (1957), listed above in the "1950s" section.
Albert Einstein
Reason and emotion counsel and supplement each other. Whoever heeds only the one, and puts aside the other, recklessly deprives himself of a portion of the aid granted us for the regulation of our conduct.
Luc de Clapiers Vauvenargues
Ownership of thought depends on the thinker not subordinating himself to a ‘ruling thought’. This is particularly difficult, argues Stirner, … for language itself is a network of ‘fixed ideas’. Truths emerge only when language is reworked and possessed individually.
John Carroll
Everything that is thought and expressed in words is one-sided, only half the truth; it all lacks totality, completeness, unity. When the Illustrious Buddha taught about the world, he had to divide it into Samsara and Nirvana, illusion and truth, into suffering and salvation. One cannot do otherwise, there is no other method for those who teach. But the world itself, being in and around us, is never one-sided. Never is a man or a deed wholly Samsara or wholly Nirvana; never is a man wholly a saint or a sinner. This only seems so because we suffer the illusion that time is something real.
