I look like a down-and-out drunk who has been picked out of the gutter in the Strand.

When you leave off dreaming, the universe ceases to exist.

Tidiness is a virtue, symmetry is often a constituent of beauty.

I wonder whether any other generation has seen such astounding revolutions of data and values as those through which we have lived. Scarcely anything material or established which I was brought up to believe was permanent and vital, has lasted. Everything I was sure or taught to be sure was impossible, has happened.

There are two processes which we adopt consciously or unconsciously when we try to prophesy. We can seek a period in the past whose conditions resemble as closely as possible those of our day, and presume that the sequel to that period will, save for some minor alterations, be similar. Secondly, we can survey the general course of development in our immediate past, and endeavor to prolong it into the near future. The first is the method the historian; the second that of the scientist. Only the second is open to us now, and this only in a partial sphere.

We do not war with races primarily as such. Tyranny is our foe. Whatever trapping or disguise it wears, whatever language it speaks, be it external or internal, we must for ever be on our guard, ever mobilized, ever vigilant, always ready to spring at its throat. In all this we march together. Not only do we march and strive shoulder to shoulder at this moment, under the fire of the enemy on the fields of war or in the air, but also in those realms of thought which are consecrated to the rights and the dignity of man.

You must sleep sometime between lunch and dinner, and no halfway measures. Take off your clothes and get into bed. That's what I always do.
