Those that are most slow in making a promise are the most faithful in the performance of it. - Jean-Jacques Rousseau

No hay derecho a matar al enemigo sino en el caso de no poderle hacer esclavo. Luego, el derecho de hacerle esclavo no viene del derecho de matarle. Por lo tanto, es un cambio inicuo hacerle comprar a costa de su libertad una vida sobre la cual nadie tiene derecho.

Bir şey öğrenmeye çalışmıyorum; artık zamanı geçti. Aslında bu denli çok bilginin, yaşamın mutluluğuna yardım ettiğini hiç görmedim; ama kendime, hiçbir güçlük duymadan zevk alacağım ve bana yıkımlarımı unutturacak tatlı ve sıradan eğlenceler arıyorum.

My illusions about the world caused me to think that in order to benefit by my reading I ought to possess all the knowledge the book presupposed. I was very far indeed from imagining that often the author did not possess it himself, but had extracted it from other books, as and when he needed it. This foolish conviction forced me to stop every moment, and to rush incessantly from one book to another; sometimes before coming to the tenth page of the one I was trying to read I should, by this extravagant method, have had to run through whole libraries. Nevertheless I stuck to it so persistently that I wasted infinite time, and my head became so confused that I could hardly see or take in anything.
