We are intelligent beings: intelligent beings cannot have been formed by a crude, blind, insensible being: there is certainly some difference between the ideas of Newton and the dung of a mule. Newton's intelligence, therefore, came from another intelligence
People must have renounced, it seems to me, all natural intelligence to dare to advance that animals are but animated machines.... It appears to me, besides, that such people can never have observed with attention the character of animals, not to have distinguished among them the different voices of need, of suffering, of joy, of pain, of love, of anger, and of all their affections. It would be very strange that they should express so well what they could not feel.
Even in those cities which seem to enjoy the blessings of peace, and where the arts florish, the inhabitants are devoured by envy, cares and anxieties, which are greater plagues than any expirienced in a town when it is under siege.
Everything happens through immutable laws, ...everything is necessary... There are, some persons say, some events which are necessary and others which are not. It would be very comic that one part of the world was arranged, and the other were not; that one part of what happens had to happen and that another part of what happens did not have to happen. If one looks closely at it, one sees that the doctrine contrary to that of destiny is absurd; but there are many people destined to reason badly; others not to reason at all others to persecute those who reason.
This self-love is the instrument of our preservation; it resembles the provision for the perpetuity of mankind: it is necessary, it is dear to us, it gives us pleasure, and we must conceal it.
The policy of man consists, at first, in endeavoring to arrive at a state equal to that of animals, whom nature has furnished with food, clothing, and shelter.
A circumstance which has always appeared wonderful to me, is that such sublime discoveries should have been made by the sole assistance of a quadrant and a little arithmetic.
You will notice that in all disputes between Christians since the birth of the Church, Rome has always favored the doctrine which most completely subjugated the human mind and annihilated reason.
The sentiment of justice is so natural, and so universally acquired by all mankind, that it seems to be independent of all law, all party, all religion.
He who is involved in ecstasies and visions, who takes dreams for reality, and his own imagination for prophesy, is a fanatical novice of great hope and promise, and will soon advance to the higher stage and kill men for the love of God.
Alas...I too have known love, that ruler of hearts, that soul of our soul: it's never brought me anything except one kiss and twenty kicks in the rump. How could such a beautiful cause produce such an abominable effect on you?
