“The Weimar Constitution is for me not a noli me tangere; I did not participate in its creation, and it is in its basic principles contrary to my political thinking…I believed that a change of the constitution was approaching, and that I could help towards this by methods which were not unnecessarily to lead through civil war. So far as concerns my attitude towards the international Social Democracy, I have to confess that at the outset I believed in the possibility to winning over part of it to national co-operation; but I have revised this opinion long ago, a long time before our conversation, in so far as the Social Democratic Party is concerned, not the German working class as such…I see clearly that a collaboration with the Social Democratic Party is impossible because it repudiates the idea of military preparedness…I do not consider a Stresemann cabinet viable, not even after its transformation. This lack of confidence I have expressed to the chancellor himself as well as to the president, and I have told them that in the long run I could not guarantee the attitude of the Reichswehr to a government in which it had no confidence…A Stresemann government cannot last without the support of the Reichswehr and of the forces standing behind it.”

Thoughts on Man's Purpose in Life (1974)
Context: I do not claim to have a magic answer. But I believe there are some basic principles of existence, propounded by thinkers through the ages, which can guide us toward the goal of finding a purpose in life.
Among these principles of existence, responsibility is the one which forces man to become involved. Acceptance of responsibility means that the individual takes upon himself an obligation. Responsibility is broad and continuous. None of us are ever free of it, even if our work is unsuccessful.
Responsibility implies a commitment to self which many are not willing to make; they are strongly attracted to accepting a course of action or direction for their lives imposed by an external source. Such a relationship absolves the individual from the personal decision-making process. He wraps himself in the security blanket of inevitability or dogma, and need not invest the enormous amounts of time, effort and, above all, the thought required to make creative decisions and meaningfully participate in the governance of his life.
Responsibility also implies a commitment to others, or as Confucius taught, each of us is meant to rescue the world. It is the business of little minds to shrink from this task or to go about it without enthusiasm. Neither art, nor science, nor any of the great works of humanity would ever come into being without enthusiasm.
The sense of responsibility for doing a job right seems to be declining. In fact, the phrase "I am not responsible" has become a standard response in our society to complaints on a job poorly done. This response is a semantic error. Generally what person means is: "I cannot be held legally liable." Yet, from a moral or ethical point of view, the person who disclaims responsibility is correct: by taking this way out he is truly not responsible; he is irresponsible.

The Crisis No. I.
1770s, The American Crisis (1776–1783)
Context: It matters not where you live, or what rank of life you hold, the evil or the blessing will reach you all. The far and the near, the home counties and the back, the rich and the poor, will suffer or rejoice alike. The heart that feels not now is dead; the blood of his children will curse his cowardice, who shrinks back at a time when a little might have saved the whole, and made them happy. I love the man that can smile in trouble, that can gather strength from distress, and grow brave by reflection. 'Tis the business of little minds to shrink; but he whose heart is firm, and whose conscience approves his conduct, will pursue his principles unto death.
My own line of reasoning is to myself as straight and clear as a ray of light. Not all the treasures of the world, so far as I believe, could have induced me to support an offensive war, for I think it murder; but if a thief breaks into my house, burns and destroys my property, and kills or threatens to kill me, or those that are in it, and to "bind me in all cases whatsoever" to his absolute will, am I to suffer it? What signifies it to me, whether he who does it is a king or a common man; my countryman or not my countryman; whether it be done by an individual villain, or an army of them? If we reason to the root of things we shall find no difference; neither can any just cause be assigned why we should punish in the one case and pardon in the other. Let them call me rebel and welcome, I feel no concern from it; but I should suffer the misery of devils, were I to make a whore of my soul by swearing allegiance to one whose character is that of a sottish, stupid, stubborn, worthless, brutish man.
