The greatest activity in the greatest stillness
CARDINAL: I shall try [to show you such an image]. I will take [the example] of boys [playing with] a top—a game known to us all, even in practical terms. A boy pitches out a top; and as he does so, he pulls it back with the string which is wound around it. The greater the strength of his arm, the faster the top is made to rotate—until it seems (while it is moving at the faster speed) to be motionless and at rest. Indeed, boys speak of it as then at rest.
So let us describe a circle, b c, which is being rotated about a point a as would the upper circle of a top; and let there be another circle, d e, which is fixed. Is it not true that the faster the movable circle is rotated, the less it seems to be moved?
BERNARD: It certainly seems true. And, as boys, this [is how] we saw [it].
