[20:4] (62) In order to prove that from such freedom no inconvenience arises, which cannot easily be checked by the exercise of the sovereign power, and that men's actions can easily be kept in bounds, though their opinions be at open variance, it will be well to cite an example. (63) Such an one is not very, far to seek. (64) The city of Amsterdam reaps the fruit of this freedom in its own great prosperity and in the admiration of all other people. (65) For in this most flourishing state, and most splendid city, men of every nation and religion live together in the greatest harmony, and ask no questions before trusting their goods to a fellow-citizen, save whether he be rich or poor, and whether he generally acts honestly, or the reverse. (66) His religion and sect is considered of no importance: for it has no effect before the judges in gaining or losing a cause, and there is no sect so despised that its followers, provided that they harm no one, pay every man his due, and live uprightly, are deprived of the protection of the magisterial authority. (20:67) On the other hand, when the religious controversy between Remonstrants and Counter-Remonstrants began to be taken up by politicians and the States, it grew into a schism, and abundantly showed that laws dealing with religion and seeking to settle its controversies are much more calculated to irritate than to reform, and that they give rise to extreme licence: further, it was seen that schisms do not originate in a love of truth, which is a source of courtesy and gentleness, but rather in an inordinate desire for supremacy, (68) From all these considerations it is clearer than the sun at noonday, that the true schismatics are those who condemn other men's writings, and seditiously stir up the quarrelsome masses against their authors, rather than those authors themselves, who generally write only for the learned, and appeal solely to reason. (69) In fact, the real disturbers of the peace are those who, in a free state, seek to curtail the liberty of judgment which they are unable to tyrannize over. (20:70) I have thus shown:- (71) I. That it is impossible to deprive men of the liberty of saying what they think. (72) II. That such liberty can be conceded to every man without injury to the rights and authority of the sovereign power, and that every man may retain it without injury to such rights, provided that he does not presume upon it to the extent of introducing any new rights into the state, or acting in any way contrary, to the existing laws. (20:73) III. That every man may enjoy this liberty without detriment to the public peace, and that no inconveniences arise therefrom which cannot easily be checked. (74) IV. That every man may enjoy it without injury to his allegiance. (75) V. That laws dealing with speculative problems are entirely useless.
