Was man, indeed, at once so powerful, so virtuous and magnificent, yet so vicious and base? He appeared at one time a mere scion of the evil principle and at another as all that can be conceived of noble and godlike. To be a great and virtuous man appeared the highest honor that can befall a sensitive being; to be base and vicious, as many on record have been, appeared the lowest degradation, a condition more abject than that of the blind mole or harmless worm. For a long time I could not conceive how one man could go forth to murder his fellow, or even why there were laws and governments; but when I heard details of vice and bloodshed, my wonder ceased, and I turned away with disgust and loathing.

We are all each of us riddles, when unknown one to the other. The plain map of human powers and purposes, helps us not at all to thread the labyrinth each individual presents in his involution of feelings, desires and capacities; and we must resemble, in quickness of feeling, instinctive sympathy, and warm benevolence, the lovely daughter of Huntley, before we can hope to judge rightly of the good and virtuous of our fellow-creatures.

— Mary Wollstonecraft Shelley

We look back to times past, and we mass them together, and say in such a year such and such events took place, such wars occupied that year, and during the next there was peace. Yet each year was then divided into weeks, days, minute, and slow-moving seconds, during which there were human minds to note and distinguish them, as now.

What do you mean? What do you demand of your captain? Are you then so easily turned from your design? Did you not call this a glorious expedition? And wherefore was it glorious? Not because the way was smooth and placid as a southern sea, but because it was full of dangers and terror; because at every new incident your fortitude was to be called forth and your courage exhibited; because danger and death surrounded it, and these you were to brave and overcome. For this was it a glorious, for this was it an honorable undertaking. You were hereafter to be hailed as the benefactors of your species; your names adored as belonging to brave men who encountered death for honor and the benefit of mankind. And now, behold, with the first imagination of danger, or, if you will, the first mighty and terrific trial of your courage, you shrink away, and are content to be handed down as men who had no strength enough to endure cold and peril; and so, poor souls, they were chilly and returned to their warm firesides. Why that requires not this preparation; ye need not have come thus far, and dragged your captain to the shame of a defeat, merely to prove yourselves cowards. Oh! Be men, or be more than men. Be steady to your purposes and firm as a rock. This ice is not made of such stuff as your hearts may be; it is mutable and cannot withstand you if you say that it shall not. Do not return to your families with the stigma of disgrace marked on your brows. Return as heroes who have fought and conquered, and who know not what it is to turn their backs on the foe.

What I ask of you is reasonable and moderate; I demand a creature of another sex, but as hideous as myself; the gratification is small, but it is all that I can receive, and it shall content me. It is true, we shall be monsters, cut off from all the world; but on that account we shall be more attached to one another. Our lives will not be happy, but they will be harmless, and free from the misery I now feel. Oh! My creator, make me happy; let me feel gratitude towards you of one benefit!

What is there in our nature that is forever urging us on towards pain and misery?

What is there so fearful as the expectation of evil tidings delayed? ... Misery is a more welcome visitant when she comes in her darkest guise and wraps us in perpetual black, for then the heart no longer sickens with disappointed hope.- The Evil Eye

What is the world, except that which we feel? Love, and hope, and delight, or sorrow and tears; these are our lives, our realities, to which we give the names of power, possession, misfortune, and death.

— Mary Wollstonecraft Shelley

When tenderness softened her heart, and the sublime feeling of universal love penetrated her, she found no voice that replied so well to hers as the gentle singing of the pines under the air of noon, and the soft murmurs of the breeze that scattered her hair and freshened her cheek, and the dashing of the waters that has no beginning or end.

Why did I not die? More miserable than man ever was before, why did I not sink into forgetfulness and rest? Death snatches away many blooming children, the only hopes of their doting parents: how many brides and youthful lovers have been one day in the bloom of health and hope, and the next a prey for worms and the decay of the tomb! Of what materials was I made, that I could thus resist so many shocks, which, like the turning of the wheel, continually renewed the torture? But I was doomed to live;
