“Well may the boldest fear and the wisest tremble when incurring responsibilities on which may depend our country's peace and prosperity, and in some degree the hopes and happiness of the whole human family.”

Thoughts on the Cause of the Present Discontents (1770)
Context: The power of discretionary disqualification by one law of Parliament, and the necessity of paying every debt of the Civil List by another law of Parliament, if suffered to pass unnoticed, must establish such a fund of rewards and terrors as will make Parliament the best appendage and support of arbitrary power that ever was invented by the wit of man. This is felt. The quarrel is begun between the Representatives and the People. The Court Faction have at length committed them. In such a strait the wisest may well be perplexed, and the boldest staggered. The circumstances are in a great measure new. We have hardly any land-marks from the wisdom of our ancestors, to guide us. At best we can only follow the spirit of their proceeding in other cases.

The Great Illusion (1910)
Context: The prosperity of a people depends upon such facts as the natural wealth of the country in which they live, their social discipline and industrial character, the result of generations, of centuries, it may be, of tradition. In addition it depends upon a special technical capacity for such-and-such a manufacture, a special aptitude for meeting the peculiarities of such-and-such a market, the efficient equipment of elaborately constructed workshops, and the existence of a population trained to given trades.

Speech at the opening ceremony of the State Bank of Pakistan, Karachi (1 July 1948)
Context: We must work our destiny in our own way and present to the world an economic system based on true Islamic concept of equality of manhood and social justice. We will thereby be fulfilling our mission as Muslims and giving to humanity the message of peace which alone can save it and secure the welfare, happiness and prosperity of mankind.

The sentence "I hope our wisdom will grow with our power, and teach us, that the less we use our power, the greater it will be." was used by US-President Barack Obama in his A New Beginning Speech.
1810s
Context: We concur in considering the government of England as totally without morality, insolent beyond bearing, inflated with vanity and ambition, aiming at the exclusive dominion of the sea, lost in corruption, of deep-rooted hatred towards us, hostile to liberty wherever it endeavors to show its head, and the eternal disturber of the peace of the world. In our estimate of Bonaparte, I suspect we differ. [... ] Our form of government is odious to him, as a standing contrast between republican and despotic rule; and as much from that hatred, as from ignorance in political economy, he had excluded intercourse between us and his people, by prohibiting the only articles they wanted from us, that is, cotton and tobacco. Whether the war we have had with England, and the achievements of that war, and the hope that we may become his instruments and partisans against that enemy, may induce him, in future, to tolerate our commercial intercourse with his people, is still to be seen. For my part, I wish that all nations may recover and retain their independence; that those which are overgrown may not advance beyond safe measures of power, that a salutary balance may be ever maintained among nations, and that our peace, commerce, and friendship, may be sought and cultivated by all. It is our business to manufacture for ourselves whatever we can, to keep our markets open for what we can spare or want; and the less we have to do with the amities or enmities of Europe, the better. Not in our day, but at no distant one, we may shake a rod over the heads of all, which may make the stoutest of them tremble. But I hope our wisdom will grow with our power, and teach us, that the less we use our power, the greater it will be.
