On Revolutionary Medicine Speech by Che Guevara to the Cuban Militia on 19 August 1960. "Because of the circumstances in which I traveled, first as a student and later as a doctor, I came into close contact with poverty, hunger and disease; with the inability to treat a child because of lack of money; with the stupefaction provoked by the continual hunger and punishment, to the point that a father can accept the loss of a son as an unimportant accident, as occurs often in the downtrodden classes of our American homeland. And I began to realize at that time that there were things that were almost as important to me as becoming famous or making a significant contribution to medical science: I wanted to help those people."
"On Development" Speech delivered by Che Guevara at the plenary session of the United Nations Conference on Trade and Development in Geneva, Switzerland on 25 March 1964. "The inflow of capital from the developed countries is the prerequisite for the establishment of economic dependence. This inflow takes various forms: loans granted on onerous terms; investments that place a given country in the power of the investors; almost total technological subordination of the dependent country to the developed country; control of a country's foreign trade by the big international monopolies; and in extreme cases, the use of force as an economic weapon in support of the other forms of exploitation."
At the Afro-Asian Conference in Algeria A speech by Che Guevara to the Second Economic Seminar of Afro-Asian Solidarity in Algiers, Algeria on 24 February 1965."The struggle against imperialism, for liberation from colonial or neocolonial shackles, which is being carried out by means of political weapons, arms, or a combination of the two, is not separate from the struggle against backwardness and poverty. Both are stages on the same road leading toward the creation of a new society of justice and plenty. ... Ever since monopoly capital took over the world, it has kept the greater part of humanity in poverty, dividing all the profits among the group of the most powerful countries. The standard of living in those countries is based on the extreme poverty of our countries. To raise the living standards of the underdeveloped nations, therefore, we must fight against imperialism. ... The practice of proletarian internationalism is not only a duty for the peoples struggling for a better future, it is also an inescapable necessity."
Footnote for Socialism and man in Cuba (1965): "Che argued that the full liberation of humankind is reached when work becomes a social duty carried out with complete satisfaction and sustained by a value system that contributes to the realization of conscious action in performing tasks. This could only be achieved by systematic education, acquired by passing through various stages in which collective action is increased. Che recognized that this to be difficult and time-consuming. In his desire to speed up this process, however, he developed methods of mobilizing people, bringing together their collective and individual interests. Among the most significant of these instruments were moral and material incentives, while deepening consciousness as a way of developing toward socialism. See Che's speeches: Homage to Emulation Prize Winners (1962) and A New Attitude to Work (1964)."
The date of birth recorded on his birth certificate was 14 June 1928, although one tertiary source, (Julia Constenla, quoted by Jon Lee Anderson), asserts that he was actually born on 14 May of that year. Constenla alleges that she was told by Che's mother, Celia de la Serna, that she was already pregnant when she and Ernesto Guevara Lynch were married and that the date on the birth certificate of their son was forged to make it appear that he was born a month later than the actual date to avoid scandal.
