Ernst Cassirer: una fundamentación biológica de la definición del ser humano como "animal simbólico"

This paper analyses the biological foundation of a new definition of human nature, as proposed by Ernst Cassirer.

It will be shown that Cassirer’s analysis considers three key elements: 1) Uexküll theoretical biology; 2) aphasia and apraxia studies; 3) and a detailed philosophical consideration of both former and latter elements.
