Not only do I use my fingers and my whole body as a single organ, but also, thanks to this unity of the body, the tactile perceptions gained through an organ are immediately translated into the language of the rest; for example, the contact of our back or chest with linen or wool remains in the memory in the form of a manual contact, and it may be said in more general terms that we can, in recollection, touch an object with parts of our body which have never actually been in contact with it.
