“Absolute, true and mathematical time, of itself, and from its own nature, flows equably, without relation to anything external”. This is the famous definition of time pronounced by Isaac Newton some three hundred years ago. One must be clear on the point that the very ability to formulate physical laws at all rests on the assumption of the uniformly flowing time. Just imagine if time itself were constantly changing. One could assert nothing concerning speed, since speed after all is defined as distance covered per unit of time, and the time lapse within each unit must naturally be assumed to remain the same.

Does Newton’s definition, however, actually offer in addition an adequate statement about the lapse of ‘subjective’ time? Newton himself characterizes subjective time in the following way: “Relative, apparent, and common time, is some sensible and external (whether accurate or unequable) measure of duration by means of motion.” If absolute time flows uniformly, and subjective time is only a measure of this absolute time, conveyed to us through our sense organs from objects in motion, then one might infer -- as many have done -- that subjective time too flows uniformly, since it conforms, as it were, subordinately to absolute time. Absolute time is primary, according to this conception of Newton’s and of those who subscribe to the viewpoint: subjective time is secondary. ~ Page 8
