Santayana's Schopenhauerian Spirit

Spirit is not an instrument but a realization, a fruition. At every stage, and wherever it peeps out through the interstices of existence, it is a contemplation of eternal things. Eternal things are not other material things by miracle existing for ever in another world; eternal things are the essences of all things here, when we consider what they are in themselves and not what, in the world of fortune, they may bring or take away from us personally. That is why piety and prayer are spiritual, when they cease to be magic operations or efforts of a celestial diplomacy: they lead us into the eternal world.
