When a man after long years of searching chances on a thought which discloses something of the beauty of this mysterious universe, he should not therefore be personally celebrated. He is already sufficiently paid by his experience of seeking and finding. In science, moreover, the work of the individual is so bound up with that of his scientific predecessors and contemporaries that it appears almost as an impersonal product of his generation.
Generations to come, it may well be, will scarce believe that such a man as this one ever in flesh and blood walked upon this Earth.
Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it. This is an illusion, and one should recognise it as such, but one ought also to stick to one’s own world-view, even at the price of seeming old-fashioned: for that world-view springs out of experiences that the younger generation has not had, and to abandon it is to kill one’s intellectual roots.
Each generation doubtless feels called upon to reform the world. Mine knows that it will not reform it, but its task is perhaps even greater. It consists in preventing the world from destroying itself.
