And this time has now come.

We, who thousands of years ago passed through the transition, from the personal, animal view of life to the socialized view, imagine that that transition was an inevitable and natural one; but this transition through which we have been passing for the last eighteen hundred years seems arbitrary, unnatural, and alarming. But we only fancy this because that first transition has been so fully completed that the practice attained by it has become unconscious and instinctive in us, while the present transition is not yet over and we have to complete it consciously.

It took ages, thousands of years, for the social conception of life to permeate men's consciousness. It went through various forms and has now passed into the region of the instinctive through inheritance, education, and habit.
