Since Marx, no one seriously denies the part played by economics in history. The relationship between economic, psychological, social and moral factors appears today, even to the adversaries of Marxism, in an altogether different light from that in which it appeared before Marx. It is the same with the role of the individual in history, and with the relationship of the individual to the masses and to society. Marxism, finally, gives us what I call the “historical sense”; it makes us conscious that we live in a world which is li-i process of changing; it enlightens us as to our possible function – and our limitations – it is this continual struggle and creation; it teaches us to integrate ourselves, with all our will, all our talents, to bring about those historical processes that are, as the case may be, necessary, inevitable or desirable. And it is thus that it allows us to confer on our isolated lives a high significance, by tying them, through a consciousness which heightens and enriches the spiritual life, to that life – collective, innumerable, and permanent – of which history is only the record.
