Nature never makes excellent things, for mean or no uses: and it is hardly to be conceived, that our infinitely wise Creator, should make so admirable a Faculty, as the power of Thinking, that Faculty which comes nearest the Excellency of his own incomprehensible Being, to be so idlely and uselesly employ'd, at least 1/4 part of its time here, as to think constantly, without remembering any of those Thoughts, without doing any good to it self or others, or being anyway useful to any other part of Creation.
John LockeAll the entertainment and talk of history is nothing almost but fighting and killing: and the honour and renown that is bestowed on conquerors (who for the most part are but the great butchers of mankind) farther mislead growing youth, who by this means come to think slaughter the laudable business of mankind, and the most heroic of virtues.
John LockeNow, I appeal to the consciences of those that persecute, torment, destroy, and kill other men upon pretence of religion, whether they do it out of friendship and kindness towards them or no? I say, if all this be done merely to make men Christians and procure their salvation, why then do they suffer whoredom, fraud, malice and such-like enormities, which (according to the Apostle) manifestly relish of heathenish corruption, to predominate so much and abound amongst their flocks and people?
John LockeA father would do well, as his son grows up, and is capable of it, to talk familiarly with him; nay, ask his advice, and consult with him about those things wherein he has any knowledge or understanding. By this, the father will gain two things, both of great moment. The sooner you treat him as a man, the sooner he will begin to be one; and if you admit him into serious discourses sometimes with you, you will insensibly raise his mind above the usual amusements of youth, and those trifling occupations which it is commonly wasted in.
John LockeHabits wear more constantly and with greatest force than reason, which, when we have most need of it, is seldom fairly consulted, and more rarely obeyed
John LockeIt is therefore worthwhile, to search out the bounds between opinion and knowledge; and examine by what measures, in things, whereof we have no certain knowledge, we ought to regulate our assent, and moderate our persuasions.
John LockeEvery man carries about him a touchstone, if he will make use of it, to distinguish substantial gold from superficial glitterings, truth from appearances. And indeed the use and benefit of this touchstone, which is natural reason, is spoiled and lost only by assuming prejudices, overweening presumption, and narrowing our minds.
