The political theory which argues that one person should hold all power is known as absolutism. It considers the king's right to rule is a divine right and the ruler gets its authority from God to do so. August of Hippo, Jacques Bossuet and Thomas Hobbes were proponent of absolutism. Thomas Hobbes believed that the absolutist rulers emerged due to the basic instincts of the humans such as fear of death and need for power. According to Hobbes , social order cannot be established unless the individuals cede the powers for the monarch so that he can use it for controlling violence and anti social elements of people.
René Descartes was a French philosopher who attributed that bodily movements and motions were propelled by tiny animal spirits.
Descartes says that these animal spirits travel throughout our bodies in the circulatory system and passes through the brain and heart, where the animal spirits signal the nerves to move our bodies.
According to Descartes, these animal spirits are the finest particles in the blood and through the principle of passion, these participles propels the movements of the spirits and heart.
