“Nothing captures the biological argument better than the famous New Age slogan: ‘Happiness begins within.’ Money, social status, plastic surgery, beautiful houses, powerful positions – none of these will bring you happiness. Lasting happiness comes only from serotonin, dopamine and oxytocin.”

“Culture tends to argue that it forbids only that which is unnatural. But from a biological perspective, nothing is unnatural. Whatever is possible is by definition also natural. A truly unnatural behaviour, one that goes against the laws of nature, simply cannot exist, so it would need no prohibition.”
― Yuval Noah Harari, Sapiens: A Brief History of Humankind

“The more I read, the more I acquire, the more certain I am that I know nothing.”

“Don't waste your time with explanations: people only hear what they want to hear.”
