From sensation to consciousness

The paper deals with the transformation of sensation concept throughout modern thinking. A particularr focus is laid on the transition of sensation from the external – the body and his surface – into the inside – the depth and darkness of human consciousness. If “nothing but a body can touch and be touched” (Lucretius, De rerum natura, I, 304), it is namely in the passivity, in the stance of “being touched”, that sensation forces a passage towards the inside, the mind, the soul, and modifies it. Modern philosophy changes the way of thinking this passage, in accordance with a new concept of subject and consciousness, and with a renewed approach to the mind-body connection. Focus of the paper are the theories of Malebranche and Condillac, as, notwithstanding the basic difference of their argumentative stance, they both propose a new path for this transition. Both Malebranche, by twisting from within meaning and extent of Cartesian dualism, and Condillac, pursuing Lockean anti-innatism, acknowledge the fundamental passivity of the sentient subject. The pervasive power ascribed to sensation is instrumental in engendering a new enlarged representation of the inner space of consciousness.
