Natura non facit saltus, perhaps; but thought makes nothing else.
Thinking
Operations of thought are like cavalry charges in a battle — they are strictly limited in number, require fresh horses, and must only be made at decisive moments.
—Whitehead
It is possible to oppose, in private, absurdities to which one is obliged to show fealty in public, but easier just to start believing them.
Endlessly we subdivide, periodize, punctuate — hours and minutes and seconds, phylum and family, genus and species, molecule and atom, hadron and quark, ancient and medieval and modern. Continuity surrounds us; yet we cannot abide it, can scarcely believe in it.
Every policy has both seen and unseen consequences, and what is unseen dwarfs what is seen.
Seeing is no longer believing; believing remains seeing.
No one will ever know what it is like to be stupid.
The choice is better thoughts or our own.
I would be more willing to speculate on the motives of others if I had a clearer understanding of my own.
To act one must disregard some of the possible consequences of one’s actions: this we call morality.
Intelligence does not improve one’s thoughts, but it does increase their variance.
