Any theory which causes solipsism to seem just as likely an explanation for the phenomena it seeks to describe ought to be held in the utmost suspicion.
Trust your feelings entirely about colour, and then, even if you arrive at no infallible colour theory, you will at least have the credit of having your own colour sense.
The US has developed two coordinate governing classes: the one, called 'business,' building cities, manufacturing and distributing goods, and holding complete and autocratic power over the livelihood of millions; the other, called 'government,' concerned with preaching and exemplification of spiritual ideals, so caught in a mass of theory, that when it wished to move in a practical world it had to do so by means of a sub rosa political machine.
For chemistry is no science form'd à priori; 'tis no production of the human mind, framed by reasoning and deduction: it took its rise from a number of experiments casually made, without any expectation of what follow'd; and was only reduced into an art or system, by collecting and comparing the effects of such unpremeditated experiments, and observing the uniform tendency thereof. So far, then, as a number of experimenters agree to establish any undoubted truth; so far they may be consider'd as constituting the theory of chemistry.
One of the big parts of my decision-making process is knowing that when you're signing up for something, you're signing up for multiple seasons, should it be successful, and in theory, you want it to be successful, but you also want to be doing something that you're enjoying.
Materialism is incomplete even as a theory of the physical world, since the physical world includes conscious organisms among its most striking occupants.
No single theory ever agrees with all the facts in its domain
The man has a theory. The woman has hipbones. Here comes Death.
Love is without a doubt the laziest theory for the meaning of life, but when it actually comes a time to do it we find just enough energy to over-complicate life again. Any devil can love, whom he himself sees as, a good person who has treated him well, but to love also the polar opposite is what separates love from fickle emotions.
Nothing in physics seems so hopeful to as the idea that it is possible for a theory to have a high degree of symmetry was hidden from us in everyday life. The physicist's task is to find this deeper symmetry.
If we accept, as we must, the theory of the indestructibility of matter, no less must we accept the indestructibility of the spirit with which matter is informed.
In theory it was, around now, Literature. Susan hated Literature. She'd much prefer to read a good book.
Philosophy is, in the last instance, class struggle in the field of theory.
There is much unexplained in the world. It behooves us to be wary at all times. Just when you think you've got the hang of it, along comes string theory, collateralized debt obligations or Björk's new album, and bam! You're as confused as you were when you first started.
An economist is someone who sees something that works in practice and wonders if it would work in theory.
If you go with Marshall McLuhan's theory that the medium is the message, as soon as you're hosting a blooper show, you're done.
Lasker thought that his rationalism rendered him immune from the surprises of chess theory.
It's easy to get next to music theory, especially between your peers and music classes and so forth. You just pay attention. I had a good ear, so I realized that printed music was just about reminding you what to play.
The sculptor, and the painter also, should be trained in these liberal arts: grammar, geometry, philosophy, medicine, astronomy, perspective, history, anatomy, theory of design, arithmetic.
To say that Nature displays intelligence doesn't make you a Christian fundamentalist. Einstein said as much, and a fascinating theory called the anthropic principle has been seriously considered by Stephen Hawking, among others.
