“Revolutionary movements do not spread by contamination but by resonance. Something that is constituted here resonates with the shock wave emitted by something constituted over there.… An insurrection is not like a plague or a forest fire — a linear process which spreads from place to place after an initial spark. It rather takes the shape of a music, whose focal points, though dispersed in time and space, succeed in imposing the rhythms of their own vibrations, always taking on more density.”

“When I consider the brief span of my life absorbed into the eternity which precedes and will succeed it—memoria hospitis unius diei praetereuntis (remembrance of a guest who tarried but a day)—the small space I occupy and which I see swallowed up in the infinite immensity of spaces of which I know nothing and which know nothing of me, I take fright and am amazed to see myself here rather than there: there is no reason for me to be here rather than there, now rather than then. Who put me here? By whose command and act were this place and time allotted to me?”

“Some girls need men to take them places. Others just click their heels, spread their own wings, and fly.”

“That ideas should freely spread from one to another over the globe, for the moral and mutual instruction of man, and improvement of his condition, seems to have been peculiarly and benevolently designed by nature, when she made them, like fire, expansible over all space, without lessening their density in any point, and like the air in which we breathe, move, and have our physical being, incapable of confinement or exclusive appropriation. Inventions then cannot, in nature, be a subject of property.”

“When we hit a nail with a hammer the whole of the shock received by the large head of the nail passes into a point without any of it being lost, although it is only a point. If the hammer and head of the nail were infinitely big, if would be just the same; the point of the nail would transmit this infinite shock at the point to which it was applied. Extreme affliction, which means physical pain, distress of the soul, and social degradation all at the same time, is a nail whose point is applied at the very center of the soul, whose head is all necessity, spreading throughout space and time”

“No great improvements in the lot of mankind are possible until a great change takes place in the fundamental constitution of their modes of thought.”
