What distinguishes the language of science from language as we ordinarily understand the word? ... What science strives for is an utmost acuteness and clarity of concepts as regards their mutual relation and their correspondence to sensory data.

Science is a wonderful thing if one does not have to earn one's living at it. One should earn one's living by work of which one is sure one is capable. Only when we do not have to be accountable to anybody can we find joy in scientific endeavor.
Pablo Casals is a very great artist. What I admire is the firm stand he has taken not only against the oppressors of his countrymen, but also against those opportunists who are always ready to compromise with the Devil. He perceives clearly that the world is in greater peril from those who tolerate or encourage evil than from those who actually commit it.
Selection [of UN delegates] by governments cannot give the peoples of the world the feeling of being fairly and proportionately represented. The moral authority of the UN would be considerable enhanced if the delegates were elected directly by the people. Were they responsible to an electorate, they would have much more freedom to follow their consciences.
Members of legislative bodies are selected by political parties, largely financed or otherwise influenced by private capitalists who, for all practical purposes, separate the electorate from the legislature. The consequence is that the representatives of the people do not in fact sufficiently protect the interests of the underprivileged sections of the population.
