The body should be strong enough to obey the mind; a good servant must be strong. I know that intemperance stimulates the passions; in course of time it also destroys the body; fasting and penance often produce the same results in an opposite way.

All sensual passions find their home in effeminate bodies; the less satisfaction they can get the keener their sting.

إنه لمنظر جميل وجليل أن ترى الإنسان يرفع نفسه من العدم بجهده الخاص ، ويبدد، بنور عقله ، تلك الظلمات التي لفته بها الطبيعة ، إنه ليرفع نفسه فوق نفسه ، وينفذ بروحه إلى أطباق السماء وينطلق كالشمس بخطوات جبارة عبر الفضاء الشاسع للكون . روسو / مقال عن الفنون والعلوم
