There is no happiness without knowledge. But knowledge of happiness is unhappy; for knowing ourselves happy is knowing ourselves passing through happiness, and having to, immediatly at once, leave it behind. To know is to kill, in happiness as in everything. Not to know, though, is not to exist.
Fernando PessoaIf this be to have sense, if to be awake Be but to see this bright, great sleep of things, For the rarer potion mine own dreams I'll take And for truth commune with imaginings
Fernando Pessoa
