patterns of particular actions handed down for the guidance of the unfree spirit. A Christian models his conduct less on the teaching than on the pattern of the Saviour. Rules have less value for telling men positively what to do than for telling them what to leave undone. Laws take on the form of universal concepts only when they forbid actions, not when they prescribe actions. Laws concerning what we ought to do must be given to the unfree spirit in wholly concrete form. Clean the street in front of your door! Pay your taxes to such and such an amount to the tax-collector! etc. Conceptual form belongs to laws which inhibit actions. Thou shalt not steal! Thou shalt not commit adultery! But these laws, too, influence the unfree spirit only by means of a concrete idea, e.g., the idea of the punishments attached by human authority, or of the pangs of conscience, or of eternal damnation, etc. Even when the motive to an action exists in universal conceptual form (e.g., Thou shalt do good to thy fellow-men! Thou shalt live so that thou promotest best thy welfare!), there still remains to be found, in the particular case, the concrete idea of the action (the relation of the concept to a content of perception). For a free spirit who is not guided by any model nor by fear of punishment, etc., this translation of the concept into an idea is always necessary. Concrete ideas are formed by us on the basis of our concepts by means of the imagination. Hence what the free spirit needs in order to realise his concepts, in order to assert himself in the world, is moral imagination. This is the source of the free spirit's action. Only those men, therefore, who are endowed with moral imagination are, properly speaking, morally productive. Those who merely preach morality, i.e., those who merely excogitate moral rules without being able to condense them into concrete ideas, are morally unproductive. They are like those critics who can explain very competently how a work of art ought to be made, but who are themselves incapable of the smallest artistic production.
