It is a curious fact that in bad days we can very vividly recall the good time that is now no more; but that in good days, we have only a very cold and imperfect memory of the bad.
Arthur SchopenhauerOne can never read too little of bad, or too much of good books: bad books are intellectual poison; they destroy the mind. In order to read what is good one must make it a condition never to read what is bad; for life is short, and both time and strength limited.
Arthur Schopenhauer
