ABSTRACT
Brodie, Sir Benjamin Lastly, physical investigation, more than anything besides, helps to teach us the actual value and right use of the Imagination-of that wondrous faculty, which, left to ramble uncontrolled, leads us astray into a wilderness of perplexities and errors, a land of mists and shadows; but which, properly controlled by experience and reflection, becomes the noblest attribute of man; the source of poetic genius, the instrument of discovery in Science, without the aid of which Newton would never have invented fluxions, nor Davy have composed the earths and alkalies, nor would Columbus have found another Continent.
