...It will give millions of answers, but none of these, no matter how sharp, have any meaning until they are viewed by life. The machine is never anything more than a servomechanism to life. Indeed, a machine cannot even exist in the absence of life.
By mechanics we mean any and all of the objects, motions or spaces which exist. Foremost of these, and foremost in any mechanical scheme, is space.
Next is energy.
Next is condensed or solidified energy, called matter.
And finally, always present in any mechanical arrangement or mechanic, that relative change of position of particles or objects known as time.
Thus we have space, energy, matter and time.
