John Locke (1632 – 1704)
Influential English philosopher and social contract theorist.
Let me give two cautions. 1) The one is, that you keep them to the practice of what you would have grow into a habit with them, by kind words, and gentle admonitions, rather as minding them of what they forget, than by harsh rebukes and chiding, as if they were wilfully guilty. 2) Another thing you are to take care of, is, not to endeavour to settle too many habits at once, lest by variety you confound them, and so perfect none. When constant custom has made any one thing easy and natural to 'em, and they practice it without reflection, you may then go on to another.
He that uses his words loosely and unsteadily will either not be minded or not understood.
And if he be too forward to venture upon his own strength and skill, and perplexity and trouble of a misadventure now and then, that reaches not his innocence, his health, or reputation, may not be an ill way to teach him more caution.
A sound mind in a sound body, is a short but full description of a happy state in this world.
The law of faith, being a covenant of free grace, God alone can appoint what shall be necessarily believed by everyone whom He will justify. What is the faith which He will accept and account for righteousness, depends wholly on his good pleasure. For it is of grace, and not of right, that this faith is accepted. And therefore He alone can set the measures of it : and what he has so appointed and declared is alone necessary. No-body can add to these fundamental articles of faith ; nor make any other necessary, but what God himself hath made, and declared to be so. And what these are which God requires of those who will enter into, and receive the benefits of the new covenant, has already been shown. An explicit belief of these is absolutely required of all those to whom the gospel of Jesus Christ is preached, and salvation through his name proposed.
He will better comprehend the foundations and measures of decency and justice, and have livelier, and more lasting impressions of what he ought to do, by giving his opinion on cases propos'd, and reasoning with his tutor on fit instances, than by giving a silent, negligent, sleepy audience to his tutor's lectures; and much more than by captious logical disputes, or set declamations of his own, upon any question. The one sets the thoughts upon wit and false colours, and not upon truth; the other teaches fallacy, wrangling, and opiniatry; and they are both of them things that spoil the judgment, and put a man out of the way of right and fair reasoning; and therefore carefully to be avoided by one who would improve himself, and be acceptable to others.
A criminal who, having renounced reason ... hath, by the unjust violence and slaughter he hath committed upon one, declared war against all mankind, and therefore may be destroyed as a lion or tyger, one of those wild savage beasts with whom men can have no society nor security. And upon this is grounded the great law of Nature, "Whoso sheddeth man's blood, by man shall his blood be shed."
The state of nature has a law of nature to govern it, which obliges every one: and reason, which is that law, teaches all mankind, who will but consult it, that being all equal and independent, no one ought to harm another in his life, health, liberty, or possessions.
A 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. For it is easy to observe, that many young men continue longer in thought and conversation of school-boys than otherwise they would, because their parents keep them at that distance, and in that low rank, by all their carriage to them.
Children should from the beginning be bred up in an abhorrence of killing or tormenting any living creature; and be taught not to spoil or destroy any thing, unless it be for the preservation or advantage of some other that is nobler.
