There is only one thing that can form a bond between men, and that is gratitude...we cannot give someone else greater power over us than we have ourselves.
There are only two cases in which war is just: first, in order to resist the aggression of an enemy, and second, in order to help an ally who has been attacked.
I acknowledge that history is full of religious wars: but we must distinguish; it is not the multiplicity of religions which has produced wars; it is the intolerant spirit animating that which believed itself in the ascendant.
I write to thee on this subject, friend, because I am angry at a book which I have just left, which is so large, that it seems to contain universal science, but it hath almost split my head, without teaching me anything.
Of all kind of authors there are none I despise more than compilers, who search every where for shreds of other men's works, which they join to their own, like so many pieces of green turf in a garden: they are not at all superior to compositors in a printing house, who range the types, which, collected together, make a book, towards which they contribute nothing but the labours of the hand. I would have original writers respected, and it seems to me a kind of profanation to take those pieces from the sanctuary in which they reside, and to expose them to a contempt they do not deserve. When a man hath nothing new to say, why does not he hold his tongue? What business have we with this double employment?"
And yet there is nothing so badly imagined: nature seems to have provided, that the follies of men should be transient, but they by writing books render them permanent. A fool ought to content himself with having wearied those who lived with him: but he is for tormenting future generations; he is desirous that his folly should triumph over oblivion, which he ought to have enjoyed as well as his grave; he is desirous that posterity should be informed that he lived, and that it should be known for ever that he was a fool. Commonly paraphrased as "An author is a fool who, not content with having bored those who have lived with him, insists on boring future generations".
History is full of religious wars; but, we must take care to observe, it was not the multiplicity of religions that produced these wars, it was the intolerating spirit which animated that one which thought she had the power of governing.
Christians are beginning to lose the spirit of intolerance which animated them: experience has shown the error of the expulsion of the Jews from Spain, and of the persecution of those Christians in France whose belief differed a little from that of the king. They have realized that zeal for the advancement of religion is different from a due attachment to it; and that in order to love it and fulfill its behests, it is not necessary to hate and persecute those who are opposed to it.
