Those who, in debate, appeal to their qualifications, argue from memory, not from understanding.

Anyone who conducts an argument by appealing to authority is not using his intelligence; he is just using his memory.

It seems that it had been destined before that I should occupy myself so thoroughly with the vulture, for it comes to my mind as a very early memory, when I was still in the cradle, a vulture came down to me, he opened my mouth with his tail and struck me a few times with his tail against my lips.

Just as food eaten without appetite is a tedious nourishment, so does study without zeal damage the memory by not assimilating what it absorbs.
