“Ideas shape the course of history.”

“A study of the history of opinion is a necessary preliminary to the emancipation of the mind.”

“The ideas of economists and political philosophers, both when they are right and when they are wrong are more powerful than is commonly understood. Indeed, the world is ruled by little else. Practical men, who believe themselves to be quite exempt from any intellectual influences, are usually slaves of some defunct economist.”

“I cannot leave this subject as though its just treatment wholly depended either on our own pledges or economic facts. The policy of reducing Germany to servitude for a generation, of degrading the lives of millions of human beings, and of depriving a whole nation of happiness should be abhorrent and detestable, - abhorrent and detestable, even if it were possible, even if it enriched ourselves, even if it did not sow the decay of the whole civilized life of Europe. Some preach it in the name of Justice. In the great events of man's history, in the unwinding of the complex fates of nations Justice is not so simple. And if it were, nations are not authorized, by religion or by natural morals, to visit on the children of their enemies the misdoings of parents of rulers.”

“When the capital development of a country becomes a by-product of the activities of a casino, the job is likely to be ill-done”

“El estudio de la economía no parece exigir ningún don especializado de un orden excepcionalmente superior. ¿No es una disciplina muy fácil comparada con las ramas superiores de la filosofía o la ciencia pura?. Una disciplina fácil de la que muy pocos sobresalen. La paradoja tal vez tenga su explicación en que el economista experto debe poseer una rara combinación de dones. Debe ser en cierta medida matemático, historiador, estadista, filosofo. Debe comprender los símbolos y hablar en palabras. Debe contemplar lo particular desde la óptica de lo general y considerar en un mismo razonamiento lo abstracto y lo concreto.Debe estudiar el presente pensando en el futuro. Ningún aspecto de la naturaleza del hombre o de sus instituciones debe quedarse al margen de su consideración. Debe ser simultáneamente decidido y desinteresado; tan distante e incorruptible como un artista y, sin embargo a veces tan cerca del suelo como un político”

“But my lord, when we addressed this issue a few years ago, didn't you argue the other side?" He said, "That's true, but when I get more evidence I sometimes change my mind. What do you do?”
