[8]: In his paper 'Kulturgeschichte und Naturwissenschaft' (Deutsche Rundschau, vol. xiii.), which is full both of original ideas and of exaggerated summary opinions, Du Bois Reymond fails to do justice to this, and altogether misjudges Petrarch's feeling for Nature. After giving this letter in proof of mediæval feeling, he goes on to say: 'Full of shame and remorse, he descends the mountain without another word. The poor fellow had given himself up to innocent enjoyment for a moment, without thinking of the welfare of his soul, and instead of gloomy introspection, had looked into the enticing outer world. Western humanity was so morbid at that time, that the consciousness of having done this was enough to cause painful inner conflict to a man like Petrarch--a man of refined feeling, and scientific, though not a deep thinker.' Even granting this, which is too tragically put, the world was on the very eve of freeing itself from this position, and Petrarch serves as a witness to the change.
