One man's life or death were but a small price to pay for the acquirement of the knowledge which I sought

I trembled, and my heart failed within me; when, on looking up, I saw, by the light of the moon, the daemon at the casement.

I am malicious because I am miserable

I saw -- with shut eyes, but acute mental vision -- I saw the pale student of unhallowed arts kneeling beside the thing he had put together. I saw the hideous phantasm of a man stretched out, and then, on the working of some powerful engine, show signs of life, and stir with an uneasy, half-vital motion.

Evil thenceforth became my good.

Life, although it may only be an accumulation of anguish, is dear to me, and I will defend it.

...we are unfashioned creatures, but half made up, if one wiser, better, dearer than ourselves - such a friend ought to be - do not lend his aid to perfectionate our weak and faulty natures.
