From the text:

“These wonderful narrations inspired me with strange feelings. 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 honour 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."
