“As for myself, I report more things than I believe; for I cannot bring myself to vouch for that which I am in doubt, nor to suppress what I have heard.”
Equidem plura transcribo quam credo; nam nec affirmare sustineo de quibus dubito, nec subducere quae accepi.

1780s, A Defence of the Constitutions of Government (1787)
Context: The right of a nation to kill a tyrant, in cases of necessity, can no more be doubted, than to hang a robber, or kill a flea. But killing one tyrant only makes way for worse, unless the people have sense, spirit and honesty enough to establish and support a constitution guarded at all points against the tyranny of the one, the few, and the many. Let it be the study, therefore, of lawgivers and philosophers, to enlighten the people's understandings and improve their morals, by good and general education; to enable them to comprehend the scheme of government, and to know upon what points their liberties depend; to dissipate those vulgar prejudices and popular superstitions that oppose themselves to good government; and to teach them that obedience to the laws is as indispensable in them as in lords and kings.

Le doute n'est pas un état bien agréable, mais l'assurance est un état ridicule.
Ce qui révolte le plus dans le Système de la nature ( après la façon de faire des anguilles avec de la farine), c'est l'audace avec laquelle il décide qu'il n'y a point de Dieu , sans avoir seulement tenté d'en prouver l'impossibilité.

“To doubt God is to doubt one's own conscience, and in consequence it would be to doubt everything.”
Letter to Fr. Pastells (4 April 1893)

Original: (it) Ogniqualvolta dovessi dubitare di ciò che stai facendo, ricorda di amare ciò che hai. Ricorda di amare ciò che fai. Ricorda di amare ciò che dai.
