“

[T]he Quantity of motive Force cannot be known without Time... Time (...abstractedly) is the continuance of any Thing in its own Being. ...Time absolutely... is Quantity, as admitting... Equality, Inequality, and Proportion... [Y]ou may ask, whether Time was not before the World was created? And if Time does not flow in the Extramundane Space, where nothing is: A mere Vacuum? ..[S]ince there was Space before the World was created, and... there now is an Extramundane, infinite Space, (where God is present)... Time existed before the World began... Some Sun might have given Light long before; and at present this, or some other like it, may diffuse Light thro' Imaginary Spaces. Time therefore does not imply an actual Existence, but only the Capacity or Possibility of the Continuance of Existence; just as Space expresses the Capacity of a Magnitude contain'd in it. ...[D]oes not Time imply Motion? I answer no... any more than it does Rest. ...[W]hether Things move on, or stand still; whether we sleep or wake, Time flows perpetually with an equal Tenor.

What It Means

This is a placeholder explanation generated by the low-overhead model. It interprets "[T]he Quantity of motive Force cannot be known without Time... Time (...abstractedly) is the continuance of any Thing in its own Being. ...Time absolutely... is Quantity, as admitting... Equality, Inequality, and Proportion... [Y]ou may ask, whether Time was not before the World was created? And if Time does not flow in the Extramundane Space, where nothing is: A mere Vacuum? ..[S]ince there was Space before the World was created, and... there now is an Extramundane, infinite Space, (where God is present)... Time existed before the World began... Some Sun might have given Light long before; and at present this, or some other like it, may diffuse Light thro' Imaginary Spaces. Time therefore does not imply an actual Existence, but only the Capacity or Possibility of the Continuance of Existence; just as Space expresses the Capacity of a Magnitude contain'd in it. ...[D]oes not Time imply Motion? I answer no... any more than it does Rest. ...[W]hether Things move on, or stand still; whether we sleep or wake, Time flows perpetually with an equal Tenor." in the context of "Isaac Barrow, Geometrical Lectures (1735) revised corrected and amended by Sir Isaac Newton, pp 3-6." to mean that wisdom is timeless.
