The sceptic will say, 'It may well be true that this system of equations is reasonable from a logical standpoint, but this does not prove that it corresponds to nature.' You are right, dear sceptic. Experience alone can decide on truth.
To be sure, it is not the fruits of scientific research that elevate a man and enrich his nature, but the urge to understand, the intellectual work, creative or receptive.
What a person thinks on his own without being stimulated by the thoughts and experiences of the other people is even in the best case rather paltry and monotonous.
Do you believe in miracles? Well, you should. In fact, life itself is a big miracle. There are so many things that are beyond our understanding. There are two ways to live: you can live as if nothing is a miracle; you can live as if everything is a miracle.
The fairest thing we can experience is the mysterious. It is the fundamental emotion that stands at the cradle of true art and true science. It is the source of all true art and science. He who knows it not and can no longer wonder, no longer feel amazement, is as good as dead, a snuffed-out candle.
No matter how we may single out a complex from nature...its theoretical treatment will never prove to be ultimately conclusive... I believe that this process of deepening of theory has no limits.
Scientific greatness is less a matter of intelligence than character; if the scientist refuses to compromise or accept incomplete answers and persists in grappling the most basic and difficult questions.
You cannot love a car the way you love a horse. The horse brings out human feelings the way machines cannot do. Things like machines may develop or neglect certain things in people ... Machines make our life impersonal and stultify certain elements in us and create an impersonal environment.
I cannot conceive of a God who rewards and punishes his creatures, or has a will of the type of which we are conscious in ourselves. An individual who should survive his physical death is also beyond my comprehension, nor do I wish it otherwise; such notions are for the fears or absurd egoism of feeble souls.
