Is tolerance for other cultures (including religions) and peoples an essential trait of Western Humanism (by Western Humanism I mean here: Renaissance Humanism and Enlightenment humanism).
By tolerance for other cultures (including religions), I mean an idea embodied in those quotations:
Everyone calls barbarism that which is not of his use. (Montaigne, 1533-1592) Chacun appelle barbarie ce qui n’est pas de son usage.
I consider all men my compatriotes. (Montaigne, 1533-1592) J'estime tous les hommes mes compatriotes.
I am a citizen of the world, known to all and to all a stranger. (Erasmus, 1466-1536) Ego mundi civis esse cupio, communis omnium, vel peregrinus magis.
There are truths on this side of the Pyrénées which are falsehoods on the other. (Pascal, 1623-1662) Vérité en deçà des Pyrénées, erreur au delà.
May all men remember that they are brothers! (Voltaire, 1694-1778) Puissent tous les hommes se souvenir qu'ils sont frères.
