I do not say this, that I think there should be no difference of opini — John Locke

"New opinions are always suspected, and usually opposed, without any other reason but because they are not already common."

"False and doubtful positions, relied upon as unquestionable maxims, keep those who build on them in the dark from truth. Such are usually the prejudices imbibed from education, party, reverence, fashion, interest, et cetera."

"He that uses his words loosely and unsteadily will either not be minded or not understood."

"I have always thought the actions of men the best interpreters of their thoughts."

"You have not that power you ought to have over him, till he comes to be more afraid of offending so good a friend than of losing some part of his future expectation."

"He that would seriously set upon the search of truth, ought in the first place to prepare his mind with a love of it. For he that loves it not, will not take much pains to get it; nor be much concerned when he misses it. There is nobody in the commonwealth of learning who does not profess himself a lover of truth: and there is not a rational creature that would not take it amiss to be thought otherwise of. And yet, for all this, one may truly say, that there are very few lovers of truth, for truths sake, even amongst those who persuade themselves that they are so. How a man may know whether he be so in earnest, is worth inquiry: and I think there is one unerring mark of it, viz. The not entertaining any proposition with greater assurance than the proofs it is built upon will warrant. Whoever goes beyond this measure of assent, it is plain receives not the truth in the love of it; loves not truth for truths sake, but for some other bye-end."
