We owe to memory not only the increase of our knowledge, and our progress in rational inquiries, but many other intellectual pleasures
Samuel JohnsonMany of our miseries are merely comparative: we are often made unhappy, not by the presence of any real evil, but by the absence of some fictitious good; of something which is not required by any real want of nature, which has not in itself any power of gratification, and which neither reason nor fancy would have prompted us to wish, did we not see it in the possession of others.
Samuel Johnson
