However, a year elapsed before I could make up my mind to engage in so disagreeable a business to the neglect of my other labors. It was the sort of thing one had to get through as quickly as possible, once it was begun. And it was not only unpleasant but quite a task. The new socialist theory appeared as the last practical result of a new philosophic system. It therefore involved an investigation of it in connection with this system and therefore of the system itself.
