Where did the world come from? The question has an answer, even though I cannot get to it. It is a good question. It is like a crime that has not been solved. There is an answer, even if police do not know it.
No doubt, the most challenging class of questions in science is the origin of things.
We can look high or we can look low in books or in journals, but the result is the same. The scientific literature has no answers to the question of the origin of the immune system.
The mystery of the beginning of all things is insoluble by us; and I for one must be content to remain an agnostic.
Don't become a mere recorder of facts, but try to penetrate the mystery of their origin.
The biggest questions that always have perplexed me are "Where do I come from?" and "Where am I going?"
We live and move and think; but we are not the creators of our own origin and existence. We are not the arbiters of every motion of our own complicated nature; we are not the masters of our own imaginations and moods of mental being.
On what can we now place our hopes of solving the many riddles which still exist as to the origin and composition of cosmic rays?
We are all of us born, live and die in the shadow of a giant question mark that refers to three questions: Where do we come from? Why? And where, oh where, are we going!
