Dual Forms of Cognition in the Middle Ages

We might say that this system of sensualism is, on the one hand, superficial, but, on the other hand, it is extraordinarily sharp. For it really attempts to observe everything, from perception to politics, in the light of sensualism and to describe it in such a way that an explanation can only be given through what the senses are able to observe and the intellect is able to combine through these sensory observations. This book was published in 1855, when a clearly defined Darwinism did not as yet exist, for Darwin's first epoch-making book only appeared in 1858.
