The instrument, in fact, finds itself originally tuned by its Maker, and may preserve its original condition by careful obedience to the stern teaching of life. The buoyancy common to all youthful and healthy natures then changes into a deeper and more solemn mood. The great primary emotions retain the original impulse, but increase their volume. Grief and disappointment are transmuted into tenderness, sympathy, and endurance. The reason, as it develops, regulates, without weakening, the primitive instincts. All the greatest, and therefore most common, sights of nature are indelibly associated with 'admiration, hope, and love;' and all increase of knowledge and power is regarded as a means for furthering the gratification of our nobler emotions. Under the opposite treatment, the character loses its freshness, and we regard the early happiness as an illusion. The old emotions dry up at their source. Grief produces fretfulness, misanthropy, or effeminacy. Power is wasted on petty ends and frivolous excitement, and knowledge becomes barren and pedantic. In this way the postulate justifies itself by producing the noblest type of character. When the 'moral being' is thus built up, its instincts become its convictions, we recognise the true voice of nature, and distinguish it from the echo of our passions. Thus we come to know how the Divine order and the laws by which the character is harmonised are the laws of morality. To possible objections it might be answered by Wordsworth that this mode of assuming in order to prove is the normal method of philosophy. 'You must love him,' as he says of the poet, Ere to you He will seem worthy of your love.
