The living subject. A comparison with the "philosophy of animality"

In his book Felice Cimatti suggests a research of "man's animality" based on a particular concept of "subjectivity": accordingly to Heidegger and the greatest part of the western thought, only human being is a subject; so animal isn't a subject and seems radically different from man; it appears as absolute "other". Any trace of animality in human being can just be a result strictly mental. But subject can otherwise shows any living being, like reminded from J. von Uexkll and H. Plessner. Through this view it is possible to see animal dimension like an indissoluble intersection with human dimension and the research of animality in human nature obtains another, deep, essential relevance.
