Science is what we understand well enough to explain to a computer. Art is everything else we do.

Art is science made clear.

Science is spectrum analysis. Art is Photosynthesis.

Science is art. It is the process of creating something that never exists before. ... It makes us ask new questions about ourselves, others; about ethics, the future.

Science is spectral analysis. Art is light synthesis.

A line is a method of expressing the effect of light upon an object; but there are no lines in Nature, everything is solid. We draw by modeling, that is to say, that we disengage an object from its setting; the distribution of the light alone gives to a body the appearance by which we know it.

Definition and division are the watchwords of science, where art is all for composition and creation.

Science and art are two separate tendencies, each representing a significant aspect of human enterprise. In general, art in all its branches is one of the vital manifestations of life and its true expression. It is futile to advocate repressing it for it is something that will never die until all life on earth is extinct.
It is wrong for us Arabs to call a halt to literature, ignoring, or ignorant of the fact that future enterprises in any nation are directed and outlined first and foremost by its literature. The way to a conscious revolt and struggle for a free, decent life is paved by literature. Through literature and art, in general, pride is awakened, ambitions are enhanced, and a psychological boost given to the morale of the citizens of a nation...A nation whose literature has become dry and sterile cannot determine what is best for itself or for humanity, no matter how high it climbs on the ladder of scientific development. (p182-3)

Science is not art. Yet, despite the lack of complete identity between art and science, there is much in common among different creative processes.

Like a work of art, we exceed our materials. Science needs art to frame the mystery, but art needs science so that not everything is a mystery. Neither truth alone is our solution, for our reality exists in plural

Art and science coincide insofar as both aim to improve the lives of men and women. The latter normally concerns itself with profit, the former with pleasure. In the coming age, art will fashion our entertainment out of new means of productivity in ways that will simultaneously enhance our profit and maximize our pleasure.

Science is the response to the demand for information, and in it we ask for the whole truth and nothing but the truth. Art is the response to the demand for entertainment, for the stimulation of our senses and imagination, and truth enters into it only as it subserves these ends.

There are two kinds of truth: the truth that lights the way and the truth that warms the heart. The first of these is science, and the second is art. Neither is independent of the other or more important than the other. Without art, science would be as useless as a pair of high forceps in the hands of a plumber. Without science, art would become a crude mess of folklore and emotional quackery. The truth of art keeps science from becoming inhuman, and the truth of science keeps art from becoming ridiculous.

All art is founded in science, and the science is of little value which does not serve as a foundation to some beneficial art. On the most sublime of all sciences, theology and ethics, is built the most important of all arts, the art of living. The abstract mathematical sciences serve as a groundwork to the arts of the land-measurer and the accountant; and in conjunction with natural philosophy, including geography and astronomy, to those of the architect, the navigator, the dialist, and many others. Of what consequence anatomy is to surgery, and that part of physiology which teaches the laws of gravitation and of motion, is to the artificer, is a matter too obvious to need illustration. The general remark might, if necessary, be exemplified throughout the whole circle of arts, both useful and elegant. Valuable knowledge, therefore, always leads to some practical skill, and is perfected in it. On the other hand, the practical skill loses much of its beauty and extensive utility which does not originate in knowledge. There is, by consequence, a natural relation between the sciences and the arts, like that which subsists between the parent and the offspring.
