“Perhaps then we must begin with such facts as are known to us from individual experience. It is necessary therefore that the person who is to study, with any tolerable chance of profit, the principles of nobleness and justice and politics generally, should have received a good moral training.”

World Within World (1951)
Context: I am for neither West nor East, but for myself considered as a self — one of the millions who inhabit the earth... If it seems absurd that an individual should set up as a judge between these vast powers, armed with their superhuman instruments of destruction I can reply that the very immensity of the means to destroy proves that judging and being judged does not lie in these forces. For supposing that they achieved their utmost and destroyed our civilization, whoever survived would judge them by a few statements. a few poems, a few témoignages [testimonies] surviving from all the ruins, a few words of those men who saw outside and beyond the means which were used and all the arguments which were marshaled in the service of those means.
Thus I could not escape from myself into some social situation of which my existence was a mere product, and my witnessing a willfully distorting instrument. I had to be myself, choose and not be chosen... But to believe that my individual freedom could gain strength from my seeking to identify myself with the "progressive" forces was different from believing that my life must be an instrument of means decided on by political leaders. I came to see that within the struggle for a juster world, there is a further struggle between the individual who cares for long-term values and those who are willing to use any and every means to gain immediate political ends — even good ends. Within even a good social cause, there is a duty to fight for the pre-eminence of individual conscience. The public is necessary, but the private must not be abolished by it; and the individual must not be swallowed up by the concept of the social man.

Deeds Rather Than Words (1963)
Context: To me, today, at age sixty-one, all prayer, by the humble or highly placed, has one thing in common: supplication for strength and inspiration to carry on the best human impulses which should bind us together for a better world. Without such inspiration, we would rapidly deteriorate and finally perish. But in our troubled time, the right of men to think and worship as their conscience dictates is being sorely pressed. We can retain these privileges only by being constantly on guard and fighting off any encroachment on these precepts. To retreat from any of the principles handed down by our forefathers, who shed their blood for the ideals we still embrace, would be a complete victory for those who would destroy liberty and justice for the individual.
