The domino theory said that if one country fell to communism, its surrounding countries would be threatened by communist expansion. The theory was introduced by Eisenhower
The domino theory relied on an idea about how ideologies spread throughout different regions. According to this theory, if one country became communist, this would have an impact on the neighbouring countries, which would lead to them also becoming communist. This idea was essential to the Cold War, as it provided a justification for the determination of the United States in eliminating all threats of communism.
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.
