A Quote by David Brewster

There are many points in the history of an invention which the inventor himself is apt to overlook as trifling, but in which posterity never fail to take a deep interest. The progress of the human mind is never traced with such a lively interest as through the steps by which it perfects a great invention; and there is certainly no invention respecting which this minute information will be more eagerly sought after, than in the case of the steam-engine.
...those experiments be not only esteemed which have an immediate and present use, but those principally which are of most universal consequence for invention of other experiments, and those which give more light to the invention of causes; for the invention of the mariner's needle, which giveth the direction, is of no less benefit for navigation than the invention of the sails, which give the motion.
Independently of the curious circumstance that such tales should be found existing in very different countries and languages, which augurs a greater poverty of human invention than we would have expected, there is also a sort of wild fairy interest in them, which makes me think them fully better adapted to awaken the imagination and soften the heart of childhood than the good-boy stories which have been in later years composed for them.
In other words, what is supposedly found is an invention whose inventor is unaware of his act of invention, who considers it as something that exists independently of him; the invention then becomes the basis of his world view and actions.
It is because of the servility of photography that I am fundamentally contemptuous of this chance invention which will never be an art but which plagiarizes nature by means of optics. (1848)
That is to say, epic poetry has been invented many times and independently; but, as the needs which prompted the invention have been broadly similar, so the invention itself has been.
I'm an inventor. I became interested in long-term trends because an invention has to make sense in the world in which it is finished, not the world in which it is started.
Ceremony is an invention to take off the uneasy feeling which we derive from knowing ourselves to be less the object of love and esteem with a fellow-creature than some other person is. It endeavours to make up, by superior attentions in little points, for that invidious preference which it is forced to deny in the greater.
Descartes constructed as noble a road of science, from the point at which he found geometry to that to which he carried it, as Newton himself did after him. ... He carried this spirit of geometry and invention into optics, which under him became a completely new art.
The sign is determined at the moment I use it and for the object of which it must form a part. For this reason I cannot determine in advance signs which never change, and which would be like writing: that would paralyze the freedom of my invention.
Next came the Patent laws. These began in England in 1624; and, in this country, with the adoption of our constitution. Before then [these?], any man might instantly use what another had invented; so that the inventor had no special advantage from his own invention. The patent system changed this; secured to the inventor, for a limited time, the exclusive use of his invention; and thereby added the fuel of interest to the fire of genius, in the discovery and production of new and useful things.
Men are apt to mistake, or at least to seem to mistake, their own talents, in hopes, perhaps, of misleading others to allow them that which they are conscious they do not possess. Thus lord Hardwicke valued himself more upon being a great minister of state, which he certainly was not, than upon being a great magistrate, which he certainly was.
Art is an invention of aesthetics, which in turn is an invention of philosophers... What we call art is a game.
There are some circumstances in which the First Amendment interest comes up against another interest that is really important and in which we have to make a decision in a particular case as to which is more important.
The sign for which I forge an image has no value if it doesn't harmonize with other signs, which I must determine in the course of my invention and which are completely peculiar to it.
Language is the most extraordinary invention in the history of humanity, the one which came before everything and which makes it possible to share everything.
Th'invention all admir'd, and each, how he to be th'inventor miss'd; so easy it seem'd once found, which yet unfound most would have thought impossible.
