“In this matter of monastic tradition, we must carefully distinguish between tradition and convention. In many monasteries there is very little living tradition, and yet the monks think themselves to be traditional. Why? Because they cling to an elaborate set of conventions. Convention and tradition may seem on the surface to be much the same thing. But this superficial resemblance only makes conventionalism all the more harmful. In actual fact, conventions are the death of real tradition as they are of all real life. They are parasites which attach themselves to the living organism of tradition and devour all its reality, turning it into a hollow formality. Tradition is living and active, but convention is passive and dead. Tradition does not form us automatically: we have to work to understand it. Convention is accepted passively, as a matter of routine. Therefore convention easily becomes an evasion of reality. It offers us only pretended ways of solving the problems of living— a system of gestures and formalities. Tradition really teaches us to live and shows us how to take full responsibility for our own lives. Thus tradition is often flatly opposed to what is ordinary, to what is mere routine. But convention, which is a mere repetition of familiar routines, follows the line of least resistance. One goes through an act, without trying to understand the meaning of it all, merely because everyone else does the same. Tradition, which is always old, is at the same time ever new because it is always reviving - born again in each new generation, to be lived and applied in a new and particular way. Convention is simply the ossification of social customs. The activities of conventional people are merely excuses for not acting in a more integrally human way. Tradition nourishes the life of the spirit: convention merely disguises its interior decay. Finally, tradition is creative. Always original, it always opens out new horizons for an old journey. Convention, on the other hand, is completely unoriginal. It is slavish imitation. It is closed in upon itself and leads to complete sterility. Tradition teaches us how to love, because it develops and expands our powers, and shows us how to give ourselves to the world in which we live, in return for all that we have received from it. Convention breeds nothing but anxiety and fear. It cuts us off from the sources of all inspiration. It ruins our productivity. It locks us up within a prison of frustrated effort. It is, in the end, only the mask for futility and for despair. Nothing could be better than for a monk to live and grow up in his monastic tradition, and nothing could be more fatal than for him to spend his life tangled in a web of monastic conventions.”
Thomas Merton wrote more than 70 books, mostly on spirituality, as well as scores of essays and reviews. Merton was a keen proponent of interfaith understanding.
Interest in his work contributed to a rise in spiritual exploration beginning in the 1960s and 1970s in the US. Merton's letters and diaries, reveal the intensity with which their author focused on social justice issues, including the civil rights movement and proliferation of nuclear arms. He had prohibited their publication for 25 years after his death. Publication raised new interest in Merton's life.
