Konrad Zacharias Lorenz was an Austrian zoologist, ethologist, and ornithologist. He shared the 1973 Nobel Prize in Physiology or Medicine with Nikolaas Tinbergen and Karl von Frisch. He is often regarded as one of the founders of modern ethology, the study of animal behavior. He developed an approach that began with an earlier generation, including his teacher Oskar Heinroth.
Marxism–Leninism is a communist ideology which was the main communist movement throughout the 20th century. It was the formal name of the state ideology adopted by the Soviet Union, its satellite states in the Eastern Bloc, and various scientific socialist countries in the Non-Aligned Movement and Third World during the Cold War as well as the Communist International after Bolshevisation. Today, Marxism-Leninism is the ideology of several communist parties and remains the official ideology of the ruling parties of China, Cuba, Laos, and Vietnam as one-party socialist republics, and of Nepal in a multiparty democracy.
Nationalism is an idea and movement that holds that the nation should be congruent with the state. As a movement, nationalism tends to promote the interests of a particular nation, especially with the aim of gaining and maintaining the nation's sovereignty (self-governance) over its homeland to create a nation state. Nationalism holds that each nation should govern itself, free from outside interference (self-determination), that a nation is a natural and ideal basis for a polity and that the nation is the only rightful source of political power. It further aims to build and maintain a single national identity, based on shared social characteristics of culture, ethnicity, geographic location, language, politics, religion, traditions and belief in a shared singular history, and to promote national unity or solidarity. Nationalism, therefore, seeks to preserve and foster a nation's traditional culture. There are various definitions of a "nation", which leads to different types of nationalism. The two main divergent forms are ethnic nationalism and civic nationalism.
Social Darwinism refers to various theories and societal practices that purported to apply biological concepts of natural selection and survival of the fittest to sociology, economics and politics, and which were largely defined by scholars in Western Europe and North America in the 1870s. Social Darwinism holds that the strong see their wealth and power increase while the weak see their wealth and power decrease. Various social Darwinist schools of thought differ on which groups of people are the strong and which are the weak, and also differ on the precise mechanisms that reward strength and punish weakness. Many such views stress competition between individuals in laissez-faire capitalism, while others, emphasizing struggle between national or racial groups, support authoritarianism, eugenics, racism, imperialism and/or fascism.
Titoism is a political philosophy most closely associated with Josip Broz Tito during the Cold War. It is characterized by a broad Yugoslav identity, workers' self-management, a political separation from the Soviet Union, and leadership in the Non-Aligned Movement.
On Aggression is a 1963 book by the ethologist Konrad Lorenz; it was translated into English in 1966. As he writes in the prologue, "the subject of this book is aggression, that is to say the fighting instinct in beast and man which is directed against members of the same species."
The social effects of evolutionary thought have been considerable. As the scientific explanation of life's diversity has developed, it has often displaced alternative, sometimes very widely held, explanations. Because the theory of evolution includes an explanation of humanity's origins, it has had a profound impact on human societies. Some have vigorously denied acceptance of the scientific explanation due to its perceived religious implications. This has led to a vigorous conflict between creation and evolution in public education, primarily in the United States.
After the Russian Revolution, in which the Bolsheviks took over the old Russian Empire in 1918, they faced enormous odds against the German Empire and eventually negotiated terms to pull out of World War I. They then went to war against both domestic and international enemies in the bitter civil war. Tsarist Russia was reorganized as the Soviet Union in 1922 with Vladimir Lenin in charge. At first, it was treated as an unrecognized pariah state because of its repudiating of tsarist debts and threats to destroy capitalism at home and around the world. By 1922, Moscow had repudiated the goal of world revolution, and sought diplomatic recognition and friendly trade relations with the capitalist world, starting with Britain and Germany. Finally in 1933, the United States gave recognition. Trade and technical help from Germany and the United States arrived in the late 1920s. After Lenin died in 1924, Joseph Stalin, became leader. He transformed the country in the 1930s into an industrial and military power. After the appeasement policy of Britain and France, the Soviet Union shifted from a strategy of antifascist collective security to one of national security. By signing the Molotov–Ribbentrop Pact with Germany in August 1939, relations improved and the Soviet Union delayed the German invasion while occupying nearby territories in Eastern Europe. Despite repeated warnings that Hitler planned to invade, Stalin was caught by surprise in June 1941 when Nazi Germany invaded the Soviet Union and reached the outskirts of Leningrad and Moscow. However, the Soviet Union proved strong enough to defeat Nazi Germany, with help from its key allies.
The history of communism encompasses a wide variety of ideologies and political movements sharing the core theoretical values of common ownership of wealth, economic enterprise and property. Most modern forms of communism are grounded at least nominally in Marxism, a theory and method conceived by Karl Marx during the 19th century. Marxism subsequently gained a widespread following across much of Europe and throughout the late 1800s its militant supporters were instrumental in a number of failed revolutions on that continent. During the same era, there was also a proliferation of communist parties which rejected armed revolution, but embraced the Marxist ideal of collective property and a classless society.
The New Soviet man or New Soviet person, as postulated by the ideologists of the Communist Party of the Soviet Union, was an archetype of a person with specific qualities that were said to be emerging as dominant among all citizens of the Soviet Union, irrespective of the country's cultural, ethnic, and linguistic diversity, creating a single Soviet people and Soviet nation.
The killer ape theory or killer ape hypothesis is the theory that war and interpersonal aggression was the driving force behind human evolution. It was originated by Raymond Dart in the 1950s; it was developed further in African Genesis by Robert Ardrey in 1961.
Criticism of atheism is criticism of the concepts, validity, or impact of atheism, including associated political and social implications. Criticisms include positions based on the history of science, philosophical and logical criticisms, findings in both the natural and social sciences, theistic apologetic arguments, arguments pertaining to ethics and morality, the effects of atheism on the individual, or the assumptions that underpin atheism.
Adolf Hitler's religious beliefs have been a matter of debate. His opinions regarding religious matters changed considerably over time. During the beginning of his political life, Hitler publicly expressed favorable opinions towards Christianity. Some historians describe his later posture as being "anti-Christian". He also criticized atheism.
Communism is a philosophical, social, political, and economic ideology and movement whose goal is the establishment of a communist society, namely a socioeconomic order structured upon the ideas of common or social ownership of all property and the absence of social classes, money, and the state. Communism is a specific, yet distinct, form of socialism. Communists usually seek a voluntary state of self-governance, but disagree on the means to this end, reflecting a distinction between a more libertarian approach of communization, revolutionary spontaneity, and workers' self-management, and a more vanguardist or Communist party-driven approach through the development of a constitutional socialist state followed by Marx's withering away of the state.
"The enemy of my enemy is my friend" is an ancient proverb which suggests that two parties can or should work together against a common enemy. The exact meaning of the modern phrase was first expressed in the Latin phrase "Amicus meus, inimicus inimici mei", which had become common throughout Europe by the early 1700s, while the first recorded use of the current English version came in 1884.
Nazism, the common name in English for National Socialism, is the ideology and practices associated with Adolf Hitler and the Nazi Party in Nazi Germany. During Hitler's rise to power in 1930s Europe, it was frequently referred to as Hitlerism. The later related term "neo-Nazism" is applied to other far-right groups with similar ideas which formed after the collapse of the Nazi regime.
The history of evolutionary psychology began with Charles Darwin, who said that humans have social instincts that evolved by natural selection. Darwin's work inspired later psychologists such as William James and Sigmund Freud but for most of the 20th century psychologists focused more on behaviorism and proximate explanations for human behavior. E. O. Wilson's landmark 1975 book, Sociobiology, synthesized recent theoretical advances in evolutionary theory to explain social behavior in animals, including humans. Jerome Barkow, Leda Cosmides and John Tooby popularized the term "evolutionary psychology" in their 1992 book The Adapted Mind: Evolutionary Psychology and The Generation of Culture. Like sociobiology before it, evolutionary psychology has been embroiled in controversy, but evolutionary psychologists see their field as gaining increased acceptance overall.
Some authors have carried out comparisons of Nazism and Stalinism. They have considered the similarities and differences between the two ideologies and political systems, the relationship between the two regimes, and why both came to prominence simultaneously. During the 20th century, the comparison of Nazism and Stalinism was made on totalitarianism, ideology, and personality cult. Both regimes were seen in contrast to the liberal-democratic Western world, emphasizing the similarities between the two.
Socialist patriotism is a form of patriotism promoted by Marxist–Leninist movements. Socialist patriotism promotes people living within Marxist–Leninist countries to adopt a "boundless love for the socialist homeland, a commitment to the revolutionary transformation of society [and] the cause of communism". Marxist–Leninists claim that socialist patriotism is not connected with nationalism, as Marxists and Marxist–Leninists denounce nationalism as a bourgeois ideology developed under capitalism that sets workers against each other. Socialist patriotism is commonly advocated directly alongside proletarian internationalism, with communist parties regarding the two concepts as compatible with each other. The concept has been attributed by Soviet writers to Karl Marx and Vladimir Lenin.
The amity-enmity complex theory was introduced by Sir Arthur Keith in his work, A New Theory of Human Evolution (1948). He posited that humans evolved as differing races, tribes, and cultures, exhibiting patriotism, morality, leadership and nationalism. Those who belong are part of the in-group, and tolerated; all others are classed as out-group, and subject to hostility: "The code of enmity is a necessary part of the machinery of evolution. He who feels generous towards his enemy... has given up his place in the turmoil of evolutionary competition."
