Letters 90.8

What! Was it philosophy that taught the use of keys and bolts? Nay, what was that except giving a hint to avarice? Was it philosophy that erected all these towering tenements, so dangerous to the persons who dwell in them? Was it not enough for man to provide himself a roof of any chance covering, and to contrive for himself some natural retreat without the help of art and without trouble? Believe me, that was a happy age, before the days of architects, before the days of builders!
