Who can tell whether the parallelogram, which in our ignorance we have defined and drawn, and the whole of whose properties we profess to know, may not be all the while panting for exterior angles, sympathetic with the interior, or sullenly repining at the fact that it cannot be inscribed in a circle?
Medicine is a science which hath been (as we have said) more professed than laboured, and yet more laboured than advanced: the labour having been, in my judgment, rather in circle than in progression. For I find much iteration, but small addition. It considereth causes of diseases, with the occasions or impulsions; the diseases themselves, with the accidents; and the cures, with the preservation.
It is a difference of opinion which does not admit of proof. We each begin probably with a little bias towards our own sex, and upon that bias build every circumstance in favour of it which has occurred within our own circle.
Most geometricians, chemists, mathematicians, and great scientists submit religion to reason only to discover a problem as unsolvable as that of squaring a circle.
There was never a time when the world began, because it goes round and round like a circle, and there is no place on a circle where it begins. Look at my watch, which tells the time; it goes round, and so the world repeats itself again and again.
Here is the vicious circle: if you feel separate from your organic life, you feel driven to survive; survival -going on living- thus becomes a duty and also a drag because you are not fully with it; because it does not quite come up to expectations, you continue to hope that it will, to crave for more time, to feel driven all the more to go on.
Do you want to improve the world? I don't think it can be done. The world is sacred. It can't be improved. If you tamper with it, you'll ruin it. If you treat it like an object, you'll lose it. There is a time for being ahead, a time for being behind; a time for being in motion, a time for being at rest; a time for being vigorous, a time for being exhausted; a time for being safe, a time for being in danger. The Master sees things as they are, without trying to control them. She lets them go their own way, and resides at the center of the circle.
An attempt at visualizing the Fourth Dimension: Take a point, stretch it into a line, curl it into a circle, twist it into a sphere, and punch through the sphere.
What is the meaning of it, Watson? said Holmes solemnly as he laid down the paper. "What object is served by this circle of misery and violence and fear? It must tend to some end, or else our universe is ruled by chance, which is unthinkable. But what end? There is the great standing perennial problem to which human reason is as far from an answer as ever.
