_Study of the Works of others._--I do not mean by this exclusively the direct exercise of the imagination in ideal creations of our own, although its frequent employment in this way, is of course necessary to its full development. But the imagination is also exercised by the study of the ideal creations of others, especially of those highly gifted minds which have adorned and enriched their age with productions of rarest value, which bear the stamp and seal of immortality. With these, in whatever department of letters or art, in poetry, oratory, music, painting, sculpture, architecture--whatever is grand, and lofty, and full of inspiration, whatever is beautiful and pleasing, whatever is of choicest worth and excellence in its own proper sphere; with these let him become familiar who seeks to cultivate in himself the faculty of the ideal. Every work of the imagination appeals to the imagination of the observer, and thus develops the faculty which it calls into exercise. No one can be familiar with the creations of Shakspeare and Milton, of Mozart and Beethoven, of Raphael and Michael Angelo, and not catch something of their inspiration. _Study of Nature._--Even more indispensable is the study of nature; and it has this advantage, that it is open to those who may not have access to the sublime works of the highest masters of art. Nature, in all her moods and phases--in her wonderful variety of elements--the grand and the lowly, the sublime and the beautiful, the terrible and the pleasing--nature in her mildest and most fearful displays of power, and also in her softest and sweetest attractions, is open to every man's observation, and he must be a close observer and a diligent student of her who would cultivate in himself the ideal element. The most gifted sons of genius, the minds most richly endowed with the power of ideal creation, have been remarkable for their love and careful study of nature.
