The three chapters which close the introduction of our book (vii.-ix.) present a lively and picturesque contrast between Folly and Wisdom---Folly more especially in the form of vice; Wisdom more generally in her highest and most universal intention. Folly is throughout concrete, an actual woman, pourtrayed with such correctness of detail that she is felt as a personal force. Wisdom, on the other hand, is only personified; she is an abstract conception; she speaks with human lips in order to carry out the parallel, but she is not a human being, known to the writer. As we shall see in the next Lecture, this high Wisdom never took a human shape until the Incarnation of our Lord Jesus Christ; Folly, unhappily, had become incarnate in myriads of instances; scarcely any city or place where men congregate was, or is, without its melancholy example. It follows from this difference between the two that the picture of Folly is a piece of vigorous realism, while the account of Wisdom is a piece of delicate idealism. Folly is historical, Wisdom is prophetic. In this chapter we are concerned with facts which the author witnessed from the window of his house looking forth through the lattice.[110] In the next chapter we shall touch on ideas which he had not seen, and could not have seen unless it were in lofty vision looking out through the lattice of the soul. In the present chapter we have an opportunity of noticing the immense value and power of pictorial delineation and concrete images in moral teaching; in the next we shall experience the peculiar fascination and inspiration of beautiful abstract conceptions, of disembodied ideals which, so far as we know at the time, are not capable of actual realization. It is important to remember this difference in order to understand why Wisdom, the shadowy contrast to that Mistress Folly who was only too concrete and familiar, shaped itself to the writer's mind as a fair and stately woman, a queenly hostess inviting simple ones to her feast; though, as Christians have learnt, the historical embodiment of Wisdom was a man, the Word of God, who of God was made unto us wisdom.
