I do not know what I may appear to the world, but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.
Interpretation
The quote reflects humility and the infinite pursuit of knowledge.
Isaac Newton uses the metaphor of a boy on the seashore to express his awareness of the vastness of knowledge that remains undiscovered. While he may have made significant discoveries, he feels that these are only small finds compared to the greater truths that lie ahead, emphasizing the importance of continuous learning and the humility that comes with recognizing the limits of one's understanding.
In practice
In a lecture on the importance of continuous education, one might quote Newton to emphasize the ongoing journey of learning.
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. For hypotheses should be employed only in explaining the properties of things, but not assumed in determining them; unless so far as they may furnish experiments.
Plato is my friend, Aristotle is my friend, but my greatest friend is truth.
His epitaph: Who, by vigor of mind almost divine, the motions and figures of the planets, the paths of comets, and the tides of the seas first demonstrated.
And from true lordship it follows that the true God is living, intelligent, and powerful; from the other perfections, that he is supreme, or supremely perfect. He is eternal and infinite, omnipotent and omniscient; that is, he endures from eternity to eternity; and he is present from infinity to infinity; he rules all things, and he knows all things that happen or can happen.
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.
Even nothing cannot last forever.
I care much more about saving the lives of mothers and babies than I do about a fancy museum somewhere.
Because what's the use of learning that I am one of a long row only - finding out that there is set down in some old book somebody just like me, and to know that I shall only act her part; making me sad, that's all. The best is not to remember your nature and your past doings have been just like thousands' and thousands', and that your coming life and doings'll be like thousands' and thousands'.
The basis of good manners is self-reliance.
Sometimes, when I hear people without experience of addiction blame addicts for their behaviour, I feel like saying to them: 'You simply don't understand - how can a child be held responsible for doing such a dreadful thing to himself?' But then again, at other times I have to acknowledge: it was done wilfully.
That the zeal for God's honor is also a dangerous passion, that the Christian must bring with him the courage to swim against the tide instead of with it... accept a good deal of loneliness, will perhaps be nowhere so clear and palpable as in the church, where he would so much like things to be different. Yet he cannot and he will not refuse to take this risk and pay this price... he belongs where the reformation of the church is underway or will again be underway.
