“Compassion for animals is intimately associated with goodness of character, and it may be confidently asserted that he who is cruel to animals cannot be a good man.”
― Arthur Schopenhauer, The Basis of Morality

“If man is not to stifle his human feelings, he must practice kindness towards animals, for he who is cruel to animals becomes hard also in his dealings with men. We can judge the heart of a man by his treatment of animals.”
― Immanuel Kant

“We seldom think of what we have, but always of what we lack.”
― Arthur Schopenhauer

“All I want is blackness. Blackness and silence.

(The actual Sylvia Plath quote from "The Moon and the Yew Tree" is:

"And the message of the yew tree is blackness –
blackness and silence.")”
― from the movie "Sylvia" (2003), incorrectly attributed to Sylvia Plath
