It may be that there is no such thing as an equable motion, whereby time may be accurately measured. All motions may be accelerated or retarded, but the true, or equable, progress of absolute time is liable to no change.
Interpretation
The essence of time cannot be altered; our perception of it may vary.
This quote by Isaac Newton reflects on the nature of time, suggesting that while our experiences and measurements may fluctuate, the fundamental progression of time itself remains constant and untouched. It indicates a profound understanding that human measurement is an imperfect reflection of a more absolute reality, thereby encouraging a deeper contemplation of how we perceive and interpret time in our lives.
In practice
In a lecture on the philosophy of time, this quote could introduce a discussion on how we measure and perceive time.
The best and safest way of philosophising seems to be, first to enquire diligently into the properties of things, and to establish those properties by experiences [experiments] and then to proceed slowly to hypotheses for the explanation of them.

My Design in this Book is not to explain the Properties of Light by Hypotheses, but to propose and prove them by Reason and Experiments: In order to which, I shall premise the following Definitions and Axioms.
It is the weight, not numbers of experiments that is to be regarded.
In the name of certainty, the greatest crimes have been committed against humanity.
...for me there is too little of life to spend most of it forcing myself into detachment from it.
When a man sells eleven ounces for twelve, he makes a compact with the devil, and sells himself for the value of an ounce.
There is no man so good, who, were he to submit all his thoughts and actions to the laws, would not deserve hanging ten times in his life.
Now I see that all relationships are virtual, even those that take place in person. Whether we use our bodies or a keyboard, it all comes down to two minds crying out from their solitude.
