I found this thought-provoking quote from Joseph Conrad. One can read this in several ways: some will find it negative; others will find it realistic.
"Life knows us not and we do not know life--we do not even know
our own thoughts. Half the words we use have no meaning whatever
and, of the other half, each man understands each word after the
fashion of his own folly and conceit. Faith is a myth, and beliefs shift
like mists on the shore; thoughts vanish; words, once pronounced,
die; and the memory of yesterday is as shadowy as the hope of
Each sentence can provoke thought or discussion, as everyone will interpret the words in his or her own manner...and have his or her own opinion.
This is a fairly concise take on human life and human thought. It is not feel-good, New Age stuff, rather the intelligent and objective evaluation of a learned man. It's conciseness is all the more surprising, considering that Conrad wrote in his second language (he was Polish, you know).
