Swiftness Quotes
The likeness of man above the throne is divided, the upper part being the colour of chashmal, the lower part like the appearance of fire. As regards the word chashmal, it has been explained to be the compound of two words chas and mal, including two different notions, viz., chash signifying "swiftness," and mal denoting "pause." The two different notions are here joined in one word in order to indicate figuratively the two different parts,-the upper part and the lower. We have already given a second explanation, namely, that chashmal includes the two notions of speach and silence; in accordance with the saying of our Sages, "At times they are silent, at times they speak."
Maimonides
Is not this Medium [æther] much rarer within the dense Bodies of the Sun, Stars, Planets, and Comets, than in the empty celestial Spaces between them? And in passing from them to great distances, doth it not grow denser and denser perpetually, and thereby cause the gravity of those great Bodies towards one another, and of their parts towards the Bodies; every Body endeavouring to go from the denser parts of the Medium towards the rarer? ...And though this Increase of density may at great distances be exceeding stow, yet if the elastick force of this Medium be exceeding great, it may suffice to impel Bodies from the denser parts of the Medium towards the rarer, with all that power which we call Gravity. And that the elastic force of this Medium is exceeding great, may be gather'd from the swiftness of its Vibrations.
Isaac Newton
The mere management of arms, though essentially requisite, was not sufficient of itself to form an accomplished knight in the times of chivalry; it was necessary for him to be endowed with beauty, as well as with strength and agility of body; he ought to be skilled in music, to dance gracefully, to run with swiftness, to excel in wrestling, to ride well, and to perform every other exercise befitting his situation. To these were to be added urbanity of manners, strict adherence to the truth, and invincible courage. Hunting and hawking skilfully were also acquirements that he was obliged to possess, and which were usually taught him as soon as he was able to endure the fatigue that they required.
Joseph Strutt
There is a law universal in nature, tending to render every reproductive being the best possible suited to its condition that its kind, or organized matter, is susceptible of, which appears intended to model the physical and mental or instinctive powers to their highest perfection and to continue them so. This law sustains the lion in his strength, the hare in her swiftness, and the fox in his wiles. As nature, in all her modifications of life, has a power of increase far beyond what is needed to supply the place of what falls by Time's decay, those individuals who possess not the requisite strength, swiftness, hardihood, or cunning, fall prematurely without reproducing - either a prey to their natural devourers, or sinking under disease, generally induced by want of nourishment, their place being occupied by the more perfect of their own kind, who are pressing on the means of subsistence.
Patrick Matthew
