Correlated with one’s own intellectual activity, part of it and growing out of it for almost everyone, is intellectual work with and upon others.  By teaching we learn.  Not to communicate one’s thoughts to others, to keep one’s thoughts to oneself as people say, is either cowardice or pride.  It is a form of sin.  It is a duty to talk, teach, explain, write, lecture, read and listen.  Every truly religious man, every good Socialist, is a propagandist.  Those who cannot write or discuss can talk, those who cannot argue can induce people to listen to others and read.  We have a belief and an idea that we want to spread, each to the utmost of his means and measure, throughout all the world.  We have a thought that we want to make humanity’s thought.  And it is a duty too that one should, within the compass of one’s ability, make teaching, writing and lecturing possible where it has not existed before.  This can be done in a hundred ways, by founding and enlarging schools and universities and chairs, for example; by making print and reading and all the material of thought cheap and abundant, by organizing discussion and societies for inquiry.

And talk and thought and study are but the more generalized aspects of duty.  The Believer may find his own special aptitude lies rather among concrete things, in experimenting and promoting experiments in collective action.  Things teach as well as words, and some of us are most expressive by concrete methods.  The Believer will work himself and help others to his utmost in all those developments of material civilization, in organized sanitation for example, all those developments that force collective acts upon communities and collective realizations into the minds of men.  And the whole field of scientific research is a field of duty calling to everyone who can enter it, to add to the permanent store of knowledge and new resources for the race.

The Mind of that Civilized State we seek to make by giving ourselves into its making, is evidently the central work before us.  But while the writer, the publisher and printer, the bookseller and librarian and teacher and preacher, the investigator and experimenter, the reader and everyone who thinks, will be contributing themselves to this great organized mind and intention in the world, many sorts of specialized men will be more immediately concerned with parallel and more concrete aspects of the human synthesis.  The medical worker and the medical investigator, for example, will be building up the body of a new generation, the body of the civilized state, and he will be doing all he can, not simply as an individual, but as a citizen, to organize his services of cure and prevention, of hygiene and selection.  A great and growing multitude of men will be working out the apparatus of the civilized state; the organizers of transit and housing, the engineers in their incessantly increasing variety, the miners and geologists estimating the
