Certainly one of the chief guarantees of freedom under any government, no matter how popular and respected, is the right of the citizens to keep and bear arms. This is not to say that firearms should not be carefully used and that definite safety rules of precaution should not be taught and enforced. But the right of the citizens to bear arms is just one guarantee against arbitrary government and one more safeguard against a tyranny which now appears remote in America, but which historically has proved to be always possible
To keep every cog and every wheel is the first precaution of intelligent tinkering.
We can easily become as much slaves to precaution as we can to fear. Although we can never rivet our fortune so tight as to make it impregnible, we may by our excessive prudence squeeze out of the life that we are guarding so anxiously all the adventurous quality that makes it worth living.
Precaution is better than cure.
"Wilderness is the raw material out of which man has hammered the artifact called civilization."
"Wilderness is a resource which can shrink but not grow... the creation of new wilderness in the full sense of the word is impossible."
"For unnumbered centuries of human history the wilderness has given way. The priority of industry has become dogma. Are we as yet sufficiently enlightened to realize that we must now challenge that dogma, or do without our wilderness? Do we realize that industry, which has been our good servant, might make a poor master?"
"The outstanding scientific discovery of the twentieth century is not television, or radio, but rather the complexity of the land organism. Only those who know the most about it can appreciate how little we know about it. The last word in ignorance is the man who says of an animal or plant: "What good is it?" If the land mechanism as a whole is good, then every part is good, whether we understand it or not. If the biota, in the course of aeons, has built something we like but do not understand, then who but a fool would discard seemingly useless parts? To keep every cog and wheel is the first precaution of intelligent tinkering."
We need to take every precaution, we need to be ever-alert, but we shouldn't go into panic mode without having things properly looked at
Don't ever give up precaution and farsightedness before attempting any work, and remember the result of negligence and nonchalance.
