According to HowStuffWorks.com, walruses can sleep and swim at the same time, too. While in the water, walruses can choose between sleeping underwater or above. A walrus can hold its breath for five minutes, just enough time for a nap. For a deeper sleep, walruses inflate spaces inside their body, called pharyngeal pouches, with up to 13 gallons of air.
Jeremy Bentham introduced the principle of utilitarianism to the penal system. He suggested that the penal system should ensure that the punishment causes more pain to the criminal than the pleasure they derived from the crime. The situation would, in turn, deter the individual from future participation in the crime.
Fundamental to the nature and activity of individuals, then, is their own well-being, and reasonâas a natural capability of the personâis considered to be subservient to this end. Bentham believed that the nature of the human person can be adequately described without mention of social relationships.
