Affection requires a firmer foundation than sympathy, and few people have a principle of action sufficiently stable to produce rectitude of feeling; … - Mary Wollstonecraft Shelley

Friendship and domestic happiness are continually praised; yet how little is there of either in the world, because it requires more cultivation of mind to keep awake affection, even in our own hearts, than the common run of people suppose. Besides, few like to be seen as they really are; and a degree of simplicity, and of undisguised confidence, which, to uninterested observers, would almost border on weakness, is the charm, nay the essence of love or friendship, all the bewitching graces of childhood again appearing.

"Poor William!" said he, "dear lovely child, he now sleeps with his angel mother! Who that had seen him bright and joyous in his young beauty, but must weep over his untimely loss! To die so miserably; to feel the murderer's grasp! How much more a murderer, that could destroy such radiant innocence! Poor little fellow! one only consolation have we; his friends mourn and weep, but he is at rest. The pang is over, his sufferings are at an end for ever. A sod covers his gentle form, and he knows no pain. He can no longer be a subject for pity; we must reserve that for his miserable survivors."

Listen to me, Frankenstein. You accuse me of murder; and yet you would, with a satisfied conscience, destroy your own creature. Oh, praise the eternal justice of man!
