“What is democracy? True democracy means the holding of power by the laboring masses. Are laborers unqualified to hold power? Yugoslavia has taken this road and proved to us that even without dictatorial rulers, big or small, the people can work even better.”

As quoted in "Some Szilardisms on War, Fame, Peace", LIFE‎ magazine, Vol. 51, no. 9 (1 September 1961), p. 79

Variant: I'm all in favor of the democratic principle that one idiot is as good as one genius, but I draw the line when someone takes the next step and concludes that two idiots are better than one genius.

Independence Day speech (1828)
Context: Where men then are free to consult experience they will correct their practice, and make changes for the better. It follows, therefore, that the more free men are, the more changes they will make. In the beginning, possibly, for the worse; but most certainly in time for the better; until their knowledge enlarging by observation, and their judgment strengthening by exercise, they will find themselves in the straight, broad, fair road of improvement. Out of change, therefore, springs improvement; and the people who shall have imagined a peaceable mode of changing their institutions, hold a surety for their melioration. This surety is worth all other excellences. Better were the prospects of a people under the influence of the worst government who should hold the power of changing it, that those of a people under the best who should hold no such power. Here, then is the great beauty of American government.

The Pathway of Peace (1923)
Context: Time has shown how illusory are alliances of great powers so far as the maintenance of peace is concerned.
In considering the use of international force to secure peace, we are again brought to the fundamental necessity of common accord. If the feasibility of such a force be conceded for the purpose of maintaining adjudications of legal right, this is only because such an adjudication would proceed upon principles commonly accepted, and thus forming part of international law, and upon the common agreement to respect the decision of an impartial tribunal in the application of such principles. This is a limited field where force is rarely needed and where the sanctions of public opinion and the demands of national honor are generally quite sufficient to bring about acquiescence in judicial awards. But in the field of conflicting national policies, and what are deemed essential interests, when the smoldering fires of old grievances have been fanned into a flame by a passionate sense of immediate injury, or the imagination of peoples is dominated by apprehension of present danger to national safety, or by what is believed to be an assault upon national honor, what force is to control the outbreak? Great powers agreeing among themselves may indeed hold small powers in check. But who will hold great powers in check when great powers disagree?.
