“The history of human knowledge has so uninterruptedly shown that to collateral, or incidental, or accidental events we are indebted for the most numerous and most valuable discoveries, that it has at length become necessary, in any prospective view of improvement, to make not only large, but the largest allowances for inventions that shall arise by chance, and quite out of the range of ordinary expectation. It is no longer philosophical to base, upon what has been, a vision of what is to be. Accident is admitted as a portion of the substructure. We make chance a matter of absolute calculation. We subject the unlooked for and unimagined, to the mathematical formulae of the schools.”

“Experience has shown, and a true philosophy will always show, that a vast, perhaps the larger, portion of truth arises from the seemingly irrelevant.”

“It is by no means an irrational fancy that, in a future existence, we shall look upon what we think our present existence, as a dream.”

“To look at a star by glances - to view it in a side-long way, by turning toward it the exterior portions of the retina (more susceptible of feeble impressions of light than the interior), is to behold the star distinctly - is to have the best appreciation of its lustre - a lustre which grows dim just in proportion as we turn our vision fully upon it.”

“Take this kiss upon the brow!And, in parting from you now,Thus much let me avow-You are not wrong, who deemThat my days have been a dream;Yet if hope has flown awayIn a night, or in a day,In a vision, or in none,Is it therefore the less gone?All that we see or seemIs but a dream within a dream.”

“Yet if Hope has flown awayIn a night, or in a day, In a vision, or in none,Is it therefore the less gone?All that we see or seemIs but a dream within a dream.”

“A skillful literary artist has constructed a tale. If wise, he has not fashioned his thoughts to accommodate his incidents; but having conceived, with deliberate care, a certain unique or single effect to be wrought out, he then invents as may best aid him in establishing this preconceived effect. If his very initial sentence tend not to the outbringing of this effect, then he has failed in his first step. In the whole composition there should be no words written, of which the tendency, direct or indirect, is not to the one pre-established design. And by such means, with such care and skill, a picture is at length painted which leaves in the mind of him who contemplates it with a kindred art, a sense of the fullest satisfaction. The idea of the tale has been presented unblemished because undisturbed: and this is an end unattainable by the novel. Undue brevity is just as exceptionable here as in the poem; but undue length is yet more to be avoided.”
