Sensivity and Suffering

"In the life of man all this appears with greatest distinctness,
illumined by the clearest knowledge. As the manifestation of the will
rises higher, the suffering becomes more apparent. In the plant there
is no sensibility and therefore no pain. In the lowest forms of
animal life, a small degree of suffering may be experienced. As the
level rises, sensitivity becomes wider and deeper. It appears in a
high degree with the complete nervous system of backboned animals.
Thus, as knowledge increases, as consciousness attains to greater
distinctness, pain also increases, and reaches its highest degree in
man. And the more intelligent and finely formed a man is, the more
pain he is open to." Schopenhauer

"Only the sensitive can face the actual, without escaping into all
kinds of conclusions, opinions, and evaluations. Only the sensitive
can be alone and this aloneness is destructive. This sensitivity is
stripped of all pleasure and so it has the austerity, not of desire
and will but of seeing and understanding." J.K.
