“All human beings, as we meet them, are commingled out of good and evil: and Edward Hyde, alone, in the ranks of mankind, was pure evil.”

“In each of us, two natures are at war – the good and the evil. All our lives the fight goes on between them, and one of them must conquer. But in our own hands lies the power to choose – what we want most to be we are.”

“but that in case of Dr. Jekyll's "disappearance or unexplained absence for any period exceeding three calendar months," the said Edward Hyde should step into the said Henry Jekyll's shoes without further delay and free from any burthen or obligation beyond the payment of a few small sums to the members of the doctor's household”

“There comes an end to all things; the most capacious measure is filled at last; and this brief condescension to evil finally destroyed the balance of my soul.”

“To cast in it with Hyde was to die a thousand interests and aspirations.”

“If he be Mr. Hyde" he had thought, "I shall be Mr. Seek.”

“Jekyll had more than a father's interest; Hyde had more than a son's indifference.”
