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.
The classical concept of human nature is easily described by Jeremy Bentham: âNature has placed mankind under the governance of two sovereign masters, pain and pleasure.â People seek to achieve pleasure and avoid pain and so they weigh up the benefits and costs of doing an act, including committing a crime.
