It would be a fatal error to consider the party as dividable into two groups, one of which is dedicated to the study and the other to action; such a distinction is deadly for the body of the party, as well as for the individual militant. The meaning of unitarism and of organic centralism is that the party develops inside itself the organs suited to the various functions, which we call propaganda, proselytism, proletarian organisation, union work, etc., up to tomorrow, the armed organisation; but nothing can be inferred from the number of comrades destined for such functions, as on principle no comrade must be left out of any of them.
