“Boundless compassion for all living beings is the surest and most certain guarantee of pure moral conduct, and needs no casuistry. Whoever is filled with it will assuredly injure no one, do harm to no one, encroach on no man's rights; he will rather have regard for every one, forgive every one, help every one as far as he can, and all his actions will bear the stamp of justice and loving-kindness.”

German philosopher and writer

Arthur Schopenhauer was a German philosopher and writer. Active in the 19th century, he is often called the “Philosopher of Pessimism.” He is best known for his 1818 book The World as Will and Representation. In that work, Schopenhauer presents the visible world as a expression of a blind, irrational will beneath appearances. He built his philosophy on Kant’s transcendental idealism, then shaped it into an atheistic system of metaphysics and ethics that stood against the German idealism of his time.
