A machine has value only as it produces more than it consumes - so check your value to the community.

Conservation is getting nowhere because it is incompatible with our Abrahamic concept of land. We abuse land because we regard it as a commodity belonging to us. When we see land as a community to which we belong, we may begin to use it with love and respect. There is no other way for land to survive the impact of mechanized man, nor for us to reap from it the esthetic harvest it is capable, under science, of contributing to culture. That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics. That land yields a cultural harvest is a fact long known, but latterly often forgotten.

Distrust even Mathematics; albeit so sublime and highly perfected, we have here a machine of such delicacy it can only work in vacuo, and one grain of sand in the wheels is enough to put everything out of gear. One shudders to think to what disaster such a grain of sand may bring a Mathematical brain. Remember Pascal.

Flight by machines heavier than air is unpractical and insignificant, if not utterly impossible.

Gates is the ultimate programming machine. He believes everything can be defined, examined, reduced to essentials, and rearranged into a logical sequence that will achieve a particular goal.

I am trying to get the hang of this new fangled writing machine, but I am not making a shining success of it. However, this is the first attempt I have ever made & yet I perceive I shall soon & easily acquire a fine facility in its use. … The machine has several virtues. I belive it will priont faster than I can write. One may lean back in his chair & work it. It piles an awful stack of words on one page. It do't muss things or scatter ink blots around. Of course it saves paper.

I'm afraid for all those who'll have the bread snatched from their mouths by these machines. ... What business has science and capitalism got, bringing ail these new inventions into the works, before society has produced a generation educated up to using them!

In the arts of life main invents nothing; but in the arts of death he outdoes Nature herself, and produces by chemistry and machinery all the slaughter of plague, pestilence and famine. … There is nothing in Man's industrial machinery but his greed and sloth: his heart is in his weapons.

Look round the world, contemplate the whole and every part of it: you will find it to be nothing but one great machine, subdivided into an infinite number of lesser machines, which again admit of subdivisions to a degree beyond what human senses and faculties can trace and explain. All these various machines, and even their most minute parts, are adjusted to each other with an accuracy which ravishes into admiration all men who have ever contemplated them. The curious adapting of means to ends, throughout all nature, resembles exactly, though it much exceeds, the productions of human contrivance-of human design, thought, wisdom, and intelligence.

My aim is to say that the machinery of the heavens is not like a divine animal but like a clock (and anyone who believes a clock has a soul gives the work the honour due to its maker) and that in it almost all the variety of motions is from one very simple magnetic force acting on bodies, as in the clock all motions are from a very simple weight.

One machine can do the work of fifty ordinary men. No machine can do the work of one extraordinary man.

Research is four things: brains with which to think, eyes with which to see, machines with which to measure, and fourth, money.

The animal frame, though destined to fulfill so many other ends, is as a machine more perfect than the best contrived steam-engine—that is, is capable of more work with the same expenditure of fuel.

The plain message physical science has for the world at large is this, that were our political and social and moral devices only as well contrived to their ends as a linotype machine, an antiseptic operating plant, or an electric tram-car, there need now at the present moment be no appreciable toil in the world.

They will have the World to be in Large, what a Watch is in Small; which is very regular, and depends only upon the just disposing of the several Parts of the Movement.

We can see that there is only one substance in the universe and that man is the most perfect one. He is to the ape and the cleverest animals what Huygens's planetary clock is to one of Julien Leroy's watches. If it took more instruments, more cogs, more springs to show or tell the time, if it took Vaucanson more artistry to make his flautist than his duck, he would have needed even more to make a speaking machine, which can no longer be considered impossible, particularly at the hands of a new Prometheus. Thus, in the same way, nature needed more artistry and machinery to construct and maintain a machine which could continue for a whole century to tell all the beats of the heart and the mind; for we cannot tell the time from the pulse, it is at least the barometer of heat and liveliness, from which we can judge the nature of the soul.

What we call man is a mechanism made up of … uncrystallized matter … all the colloid matter of his mechanism is concentrated in a countless number of small cells. … [T]hese cells [are] dwelling places, communes, a walled town within which are many citizens. ... [T]hese are the units of life and when they pass out into space man as we think we know him is dead, a mere machine from which the crew have left,so to speak. ... [T]hese units are endowed with great intelligence. They have memories, they must be divided into countless thousands of groups, most are workers, there are directing groups. Some are chemists, they manufacture the most complicated chemicals that are secreted by the glands.

When a body acts upon another one, it is always immediately or through some intermediate body; this intermediate body is in general what one calls a machine.

When a machine begins to run without human aid, it is time to scrap it - whether it be a factory or a government.

You say Beasts are Machines like Watches? But put the Machine called a Dog, and the Machine called a Bitch to one another for some time, and there may result another little Machine; whereas two Watches might be together all their Life-time, without ever producing a third Watch. Now Madam de B— and I think, according to our Philosophy, that all things which being but two, are endued with the Virtue of making themselves three, are of a much higher Nature than a Machine.

[I] grew up as a disciple of science. I know its fascination. I have felt the godlike power man derives from his machines.

[T]he human desire to escape the flesh, which took one form in asceticism, might take another form in the creation of machines. Thus, the wish to rise above the bestial body manifested itself not only in angels but in mechanical creatures. Certainly, once machines existed, humans clearly attached to them feelings of escape from the flesh.
