A New View of Society (1813-1816)
Context: All that is now requisite, previous to withdrawing the last mental bandage by which hitherto the human race has been kept in darkness and misery, is, by calm and patient reasoning to tranquillize the public mind, and thus prevent the evil effects which otherwise might arise from the too sudden prospect of freely enjoying rational liberty of mind. To withdraw that bandage without danger, reason must be judiciously applied to lead men of every sect (for all have been in part abused to reflect that if untold myriads of beings, formed like themselves, have been so grossly deceived as they believe them to have been, what power in nature was there to prevent them from being equally deceived? Such reflections, steadily pursued by those who are anxious to follow the plain and simple path of reason, will soon make it obvious that the inconsistencies which they behold in all other sects out of their own pale, are precisely similar to those which all other sects can readily discover within that pale. It is not, however, to be imagined, that this free and open exposure of the gross errors in which the existing generation has been instructed, should be forthwith palatable to the world; it would be contrary to reason to form any such expectations. Yet, as evil exists, and as man cannot be rational, nor of course happy, until the cause of it shall be removed; the writer, like a physician who feels the deepest interest in the welfare of his patient, has hitherto administered of this unpalatable restorative the smallest quantity which he deemed sufficient for the purpose. He now waits to see the effects which that may produce. Should the application not prove of sufficient strength to remove the mental disorder, he promises that it shall be increased, until sound health to the public mind be firmly and permanently established.

Variant: Total security has never been available to anyone. To expect it is unrealistic; to imagine that it can exist is to invite disaster. I believe the most important aim for humanity at present is to avoid war, dictatorship, and their awful consequences.
Better a Shield Than A Sword : Perspectives On Defense And Technology (1987), p. 241
Context: The preservation of peace and the improvement of the lot of all people require us to have faith in the rationality of humans. If we have this faith and if we pursue understanding, we have not the promise but at least the possibility of success. We should not be misled by promises. Humanity in all its history has repeatedly escaped disaster by a hair's breadth. Total security has never been available to anyone. To expect it is unrealistic; to imagine that it can exist is to invite disaster. What we do have in our technological capacities is an opportunity to use our inventiveness, our creativity, our wisdom and our understanding of our fellow beings to create a future world that is a little better than the one in which we live today.

Die Wahrheit widerspricht unserer Natur, der Irrthum nicht, und zwar aus einem sehr einfachen Grunde: die Wahrheit fordert, daß wir uns für beschränkt erkennen follen, der Irrthum schmeichelt uns. wir seien auf ein- oder die andere Weise unbegränzt.

Context: When thou art offended at any man's fault, forthwith turn to thyself and reflect in what manner thou doest error thyself... For by attending to this thou wilt quickly forget thy anger, if this consideration is also added, that the man is compelled; for what else could he do? or, if thou art able, take away from him the compulsion.
