The Keeper of Sheep (O Guardador de Rebanhos)
[The heteronym] Caeiro is an absolute affirmation of existence and hence his words strike us as truths from another age, that age in which everything was one in the same. Sensible and untouchable present: we hardly name it and it evaporates! The mask of innocence which Caeiro turns to us is not that of wisdom: to be wise is to resign ourself to the knowledge that we are not innocent. Pessoa, who did know it, was nearer to wisdom.  --Octavio Paz
