We are stopping at the very point where a boundless ocean of enquiries opens out for our questioning.
I agree that the view of Nature which I have maintained in these lectures is not a simple one.

Nature appears as a complex system whose factors are dimly discerned by us.

But, as I ask you, Is not this the very truth?
Should we not distrust the jaunty assurance with which every age prides itself that it at last has hit upon the ultimate concepts in which all that happens can be formulated?
The aim of science is to seek the simplest explanations of complex facts.

We are apt to fall into the error of thinking that the facts are simple because simplicity is the goal of our quest.

The guiding motto in the life of every natural philosopher should be, Seek simplicity and distrust it..
