Dual Forms of Cognition in the Middle Ages

Generally speaking, the year 1858 was very trenchant in the more recent spiritual evolution. Darwin's “Origin of the Species” appeared at that time. Spectral analysis also arose at that time within the evolution of humanity, and this has given rise to the conception that the universe consists of the same material substances as those of terrestrial existence. In that year the first attempt was made to deal with the aesthetic sphere in an external, empiric manner, a subject which in the past had always been treated in a spiritual-intellectual manner. Gustav Theodor Fechner's “Introduction to Aesthetics” was published in 1858. Finally, the attempt was made to apply this manner of thinking, which is contained in all the above examples, to social life. The first more important economic book of Carl Marx also appeared in that year. This fourth phenomenon of the modern materialistic life of the spirit thus appears not only in the same period, but in the same year of that period. As stated, certain things have preceded all this, for instance, Czolbe's “Sensualism”.
