But with these adjustments, imperceptible in ordinary use, the laws deal with fundamental physical quantities which we know very well and wish to correlate.
The measurement of time was known to all civilised nations long before the laws were thought of.

It is this time as thus measured that the laws are concerned with.

Also they deal with the space of our daily life.
When we approach to an accuracy of measurement beyond that of observation, adjustment is allowable.

But within the limits of observation we know what we mean when we speak of measurements of space and measurements of time and uniformity of change.

It is for science to give an intellectual account of what is so evident in sense-awareness.
It is to me thoroughly incredible that the ultimate fact beyond which there is no deeper explanation is that mankind has really been swayed by an unconscious desire to satisfy the mathematical formulae which we call the Laws of Motion, formulae completely unknown till the seventeenth century of our epoch.
The correlation of the facts of sense-experience effected by the alternative account of nature extends beyond the physical properties of motion and the properties of congruence.
