How many winds of doctrine we have known in recent decades, how many ideological currents, how many ways of thinking. The small boat of thought of many Christians has often been tossed about by these waves - thrown from one extreme to the other: from Marxism to liberalism, even to libertinism; from collectivism to radical individualism; from atheism to a vague religious mysticism; from agnosticism to syncretism, and so forth. Every day new sects are created and what Saint Paul says about human trickery comes true, with cunning which tries to draw those into error (cf Ephesians 4, 14). Having a clear Faith, based on the Creed of the Church, is often labeled today as a fundamentalism. Whereas, relativism, which is letting oneself be tossed and 'swept along by every wind of teaching', looks like the only attitude acceptable to today's standards. We are moving towards a dictatorship of relativism which does not recognize anything as certain and which has as its highest goal one's own ego and one's own desires. However, we have a different goal: the Son of God, true man. He is the measure of true humanism. Being an 'Adult' means having a faith which does not follow the waves of today's fashions or the latest novelties. A faith which is deeply rooted in friendship with Christ is adult and mature. It is this friendship which opens us up to all that is good and gives us the knowledge to judge true from false, and deceit from truth.

~ Pope Benedict Xvi

[Letter to his wife, Natalia Sedova]In addition to the happiness of being a fighter for the cause of socialism, fate gave me the happiness of being her husband. During the almost forty years of our life together she remained an inexhaustible source of love, magnanimity, and tenderness. She underwent great sufferings, especially in the last period of our lives. But I find some comfort in the fact that she also knew days of happiness.For forty-three years of my conscious life I have remained a revolutionist; for forty-two of them I have fought under the banner of Marxism. If I had to begin all over again I would of course try to avoid this or that mistake, but the main course of my life would remain unchanged. I shall die a proletarian revolutionist, a Marxist, a dialectical materialist, and, consequently, an irreconcilable atheist. My faith in the communist future of mankind is not less ardent, indeed it is firmer today, than it was in the days of my youth.Natasha has just come up to the window from the courtyard and opened it wider so that the air may enter more freely into my room. I can see the bright green strip of grass beneath the wall, and the clear blue sky above the wall, and sunlight everywhere. Life is beautiful. Let the future generations cleanse it of all evil, oppression and violence, and enjoy it to the full.

~ Leon Trotsky

When asked whether or not we are Marxists, our position is the same as that of a physicist, when asked if he is a “Newtonian” or of a biologist when asked if he is a “Pasteurian.”There are truths so evident, so much a part of the peoples’ knowledge, that it is now useless to debate them. One should be a “Marxist” with the same naturalness with which one is a “Newtonian” in physics or a “Pasteurian.” If new facts bring about new concepts, the latter will never take away that portion of truth possessed by those that have come before.Such is the case, for example, of “Einsteinian” relativity or of Planck’s quantum theory in relation to Newton’s discoveries. They take absolutely nothing away from the greatness of the learned Englishman. Thanks to Newton, physics was able to advance until it achieved new concepts of space. The learned Englishman was the necessary stepping-stone for that.Obviously, one can point to certain mistakes of Marx, as a thinker and as an investigator of the social doctrines and of the capitalist system in which he lived. We Latin Americans, for example, cannot agree with his interpretation of Bolivar, or with his and Engels’ analysis of the Mexicans, which accepted as fact certain theories of race or nationality that are unacceptable today.But the great men who discover brilliant truths live on despite their small faults and these faults serve only to show us they were human. That is to say, they were human beings who could make mistakes, even given the high level of consciousness achieved by these giants of human thought.This is why we recognize the essential truths of Marxism as part of humanity’s body of cultural and scientific knowledge. We accept it with the naturalness of something that requires no further argument.

~ Ernesto Che Guevara

Nowhere do “politicians” form a more separate and powerful section of the nation than precisely in North America. There, each of the two major parties which alternatively succeed each other in power is itself in turn controlled by people who make a business of politics, who speculate on seats in the legislative assemblies of the Union as well as of the separate states, or who make a living by carrying on agitation for their party and on its victory are rewarded with positions. It is well known how the Americans have been trying for thirty years to shake off this yoke, which has become intolerable, and how in spite of it all they continue to sink ever deeper in this swamp of corruption. It is precisely in America that we see best how there takes place this process of the state power making itself independent in relation to society, whose mere instrument it was originally intended to be. Here there exists no dynasty, no nobility, no standing army, beyond the few men keeping watch on the Indians, no bureaucracy with permanent posts or the right to pensions. And nevertheless we find here two great gangs of political speculators, who alternately take possession of the state power and exploit it by the most corrupt means and for the most corrupt ends – and the nation is powerless against these two great cartels of politicians, who are ostensibly its servants, but in reality dominate and plunder it.

~ Frederick Engels

Take the example of our spinner. We have seen that, to daily reproduce his labouring power, he must daily reproduce a value of three shillings, which he will do by working six hours daily. But this does not disable him from working ten or twelve or more hours a day. But by paying the daily or weekly value of the spinner's labouring power the capitalist has acquired the right of using that labouring power during the whole day or week. He will, therefore, make him work say, daily, twelve hours. Over and above the six hours required to replace his wages, or the value of his labouring power, he will, therefore, have to work six other hours, which I shall call hours of surplus labour, which surplus labour will realize itself in a surplus value and a surplus produce. If our spinner, for example, by his daily labour of six hours, added three shillings' value to the cotton, a value forming an exact equivalent to his wages, he will, in twelce hours, add six shillings' worth to the cotton, and produce a proportional surplus of yarn. As he has sold his labouring power to the capitalist, the whole value of produce created by him belongs to the capitalist, the owner pro tem. of his labouring power. By advancing three shillings, the capitalist will, therefore, realize a value of six shillings, because, advancing a value in which six hours of labour are crystallized. By repeating this same process daily, the capitalist will daily advance three shillings and daily pocket six shillings, one half of which will go to pay wages anew, and the other half of which will form surplus value, for which the capitalist pays no equivalent. It is this sort of exchange between capital and labour upon which capitalistic production, or the wages system, is founded, and which must constantly result in reproducing the working man as a working man, and the capitalist as a capitalist.
