“The outlook of a Bruno, a Kepler, or a Galileo is determined by the idea of a comprehensive, all-embracing unity of the physical world. The same law governs the courses of the stars, the falling of stones, and the flight of birds. This homogenization of the physical world with respect to the validity of law deprives the division of physical objects into rigid abstractly defined classes of the critical significance it had for Aristotelian physics, in which membership in a certain conceptual class was considered to determine the physical nature of an object.”

"The Magic of Science" in Imperial Oil Review (Spring, 1994) http://sites.utoronto.ca/jpolanyi/public_affairs/public_affairs4f.html.
Context: It is not the laws of physics that make science possible but the unprovable proposition that there exists a grand design underlying the physical world. And not just any old "grand design" but one that is accessible to the limited senses and modest reasoning powers of the species to which we belong. Scientists subscribe with such conviction to this article of faith that they are willing to commit a lifetime to the pursuit of scientific discovery. It is hardly surprising that an activity so magical is also undefinable. Science is what scientists do. And what they do is look around themselves for messages written in the sky, the earth, the oceans and all living things – messages that tell of the unity of creation. These messages have been there – unseen, though at times written in letters miles high – since the dawn of history. But we have just passed through an epoch in which, quite suddenly, scientists seem to have learnt speed reading. Discoveries have been coming at an unprecedented pace. In the wake of such a period it is common to consider that we may be approaching the point where all that is readable in nature will have been read. We should be skeptical of such claims. Success in reading some messages brings with it a temporary blindness to others. We forget that between the words written in black in nature's book there are likely to be messages of equal importance written in white. It is a truism that success in science comes to the individuals who ask the right questions.

The Clerk's Vision (1949)
Context: The world stretches out before me, the vast world of the big, the little, and the medium. Universe of kings and presidents and jailors, of mandarins and pariahs and liberators and liberated, of judges and witnesses and the condemned: stars of the first, second, third and nth magnitudes, planets, comets, bodies errant and eccentric or routine and domesticated by the laws of gravity, the subtle laws of falling, all keeping step, all turning slowly or rapidly around a void. Where they claim the central sun lies, the solar being, the hot beam made out of every human gaze, there is nothing but a hole and less than a hole: the eye of a dead fish, the giddy cavity of the eye that falls into itself and looks at itself without seeing. There is nothing with which to fill the hollow center of the whirlwind. The springs are smashed, the foundations collapsed, the visible or invisible bonds that joined one star to another, one body to another, one man to another, are nothing but a tangle of wires and thorns, a jungle of claws and teeth that twist us and chew us and spit us out and chew us again. No one hangs himself by the rope of a physical law. The equations fall tirelessly into themselves.
And in regard to the present matter, if the present matters: I do not belong to the masters. I don't wash my hands of it, but I am not a judge, nor a witness for the prosecution, nor an executioner. I do not torture, interrogate, or suffer interrogation. I do not loudly plead for leniency, nor wish to save myself or anyone else. And for all that I don't do and for all that they do to us, I neither ask forgiveness nor forgive. Their piety is as abject as their justice. Am I innocent? I'm guilty. Am I guilty? I'm innocent. (I'm innocent when I'm guilty, guilty when I'm innocent. I'm guilty when … but that is another song. Another song? It's all the same song.) Guilty innocent, innocent guilty, the fact is I quit.
