When you're 20 you care what everyone thinks, when you're 40 you stop caring what everyone thinks, when you're 60 you realize no one was ever thinking about you in the first place. You have enemies? Good. That means you've stood up for something, sometime in your life.
Laws just or unjust may govern men's actions. Tyrannies may restrain or regulate their words. The machinery of propaganda may pack their minds with falsehood and deny them truth for many generations of time. But the soul of man thus held in trance or frozen in a long night can be awakened by a spark coming from God knows where and in a moment the whole structure of lies and oppression is on trial for its life.
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.
If I stay on for the time being, bearing the burden at my age, it is not because of love for power or office. I have had an ample share of both. If I stay it is because I have a feeling that I may, through things that have happened, have an influence about what I care about above all else, the building of a sure and lasting peace.
