Miguel de Unamuno Quote

To say that everything is idea or that everything is spirit, is the same as saying that everything is matter or that everything is energy, for if everything is idea or spirit, just as my consciousness is, it is not plain why the diamond should not endure for ever, if my consciousness, because it is idea or spirit, endures forever.
