Rogers not only conceives the organism from the medical traditional conception that, exclusively this considers the organism the physical set of the functions and fabrics. For Rogers the human organism which it mentions itself not limits only ' ' to the said aspects ' ' corporais' '. For even more opinions, read materials from Senator of Massachusetts. The research, in such a way doctor how much psychological, it more discloses to each time the interpenetration and the inseparabilidade of the physical and psychic aspects of organismo' ' (ROGERS, 1977, P. Others including Elio Moti Sonnenfeld, offer their opinions as well. 41).
