In your expurgation, of the popular errors, you must be sure that the truth they contain, is in some form as strongly, as _effectively_ composed in your text, or the popular error is truer and better than the truth with which you would replace it. This is a master who will have no other kind of teaching in his school. His scholars must go so far in their learning as to be able to come back to this popular belief, and account for it and understand it; they must be as wise as the peasant again, and be able to start with him, from his starting point, before they can get any diploma in this School of _Advancement_, or leave to practise in it. But when the old is already ruinous and decaying, and oppressing and keeping back the new,--when the vitality is gone out of it, and it has become deadly instead, when the new is struggling for new forms, the man of science though never so conservative from inclination and principle, will not be wanting to himself and to the state in this emergency. He 'loves the _fundamental part of state_ more' than in _such_ a crisis he will 'doubt the change of it,' and will not 'fear to jump a body with a dangerous physic, that's sure of death without it.' First of all then, the condition of this lamp of tradition, that is to burn on for ages, is, that it shall be able to adapt itself to the successive stages of the advancement it lights. It is the inevitable condition of this school which begins with the present, which begins with the people, which descends to the lowest stage of the contemporary popular belief, and takes in the many-headed monster himself, without any trimming at all, for its audience,--it is the first condition of such a school, conducted by a man of science, that it shall have its proper grades of courts and platforms, its selecter and selectest audiences. There must be landing places in the ascent, points of rendezvous agreed on, where 'the delicate collateral sounds' are heard, which only those who ascend can hear. There is no jar,--there is no forced advancement in this school; there is no upward step for any, who have not first been taught to see it, who have not, indeed, already taken it. For it is an artist's school, and not a pedant's, or a vague speculator's, who knows not how to converge his speculation, even upon his mode of tradition.
