"Being now resolved to be a poet, I saw every thing with a new purpose; my sphere of attention was suddenly magnified: no kind of knowledge was to be overlooked. I ranged mountains and deserts for images and resemblances, and pictured upon my mind every tree of the forest and flower of the valley. I observed, with equal care, the crags of the rock and the pinnacles of the palace. Sometimes I wandered along the mazes of the rivulet, and sometimes watched the changes of the summer clouds. To a poet, nothing can be useless. Whatever is beautiful, and whatever is dreadful, must be familiar to his imagination: he must be conversant with all that is awfully vast, or elegantly little. The plants of the garden, the animals of the wood, the minerals of the earth, and meteors of the sky, must all concur to store his mind with inexhaustible variety; for every idea is useful for the enforcement or decoration of moral or religious truth; and he, who knows most, will have most power of diversifying his scenes, and of gratifying his reader with remote allusions and unexpected instruction. "All the appearances of nature I was, therefore, careful to study, and every country, which I have surveyed, has contributed something to my poetical powers." "In so wide a survey," said the prince, "you must surely have left much unobserved. I have lived till now, within the circuit of these mountains, and yet cannot walk abroad without the sight of something, which I had never beheld before, or never heeded." "The business of a poet," said Imlac, "is to examine, not the individual, but the species; to remark general properties and large appearances: he does not number the streaks of the tulip, or describe the different shades in the verdure of the forest. He is to exhibit, in his portraits of nature, such prominent and striking features, as recall the original to every mind; and must neglect the minuter discriminations, which one may have remarked, and another have neglected, for those characteristicks which are alike obvious to vigilance and carelessness.
