Virtue is harder to be got than knowledge of the world; and, if lost in a young man, is seldom recovered. - John Locke

God gave the World to Men in Common; But since he gave it them for their benefit, and the greatest Conveniencies of life they were capable to draw from it, it cannot be supposed he meant it should always remain common and uncultivated. He gave it to the use of the industrious and Rational, (and Labour was to be his Title to it;) not to the fancy or covetousness of the quarrelsome and contentious.

But if Adam and Eve (when they were alone in the world) instead of their ordinary night's sleep, had passed the whole twenty-four hours in one continued sleep, the duration of that twenty-four hours had been irrecoverably lost to them, and been for ever left out of their account of time.

I am sure the principal end why we are to get knowledge here, is to make use of it for the benefit of ourselves and others in this world; but if by gaining it we destroy our health, we labour for a thing that will be useless in our hands, and if by harnessing our bodies (though with a design to render ourselves more useful)we deprive ourselves of the abilities and opportunities of doing that good we might have done with a meaner talent, which God thought sufficient for us by having denied us the strength to iprove it to that pitch which men of higher constitutions can attain to, we rob God of so much service, and our neighbor of all that help, which, in a state of health, with moderate knowledge, we might have been able to perform. He that sinks his vessel by overloading it, though it be with gold and silver and precious stones, will gives his owner but an ill account of his voyage.
