In classical logic, a contradiction consists of a logical incompatibility between two or more propositions. It occurs when the propositions, taken together, yield two conclusions which form the logical, usually opposite inversions of each other. Illustrating a general tendency in applied logic, Aristotle’s law of noncontradiction states that “One cannot say of something that it is and that it is not in the same respect and at the same time.”
By extension, outside of classical logic, one can speak of contradictions between actions when one presumes that their motives contradict each other.
By creation of a paradox, Plato's Euthydemus dialogue demonstrates the need for the notion of contradiction. In the ensuing dialogue Dionysodorus denies the existence of "contradiction", all the while that Socrates is contradicting him:
Indeed, Dionysodorus agrees that "there is no such thing as false opinion . . . there is no such thing as ignorance" and demands of Plato to "Refute me." Socrates responds "But how can I refute you, if, as you say, to tell a falsehood is impossible?".
Clinton Richard Dawkins, FRS, FRSL (born 26 March 1941), known as Richard Dawkins, is a British ethologist, evolutionary biologist and author. He is an emeritus fellow of New College, Oxford, and was the University of Oxford's Professor for Public Understanding of Science from 1995 until 2008.
Dawkins came to prominence with his 1976 book The Selfish Gene, which popularised the gene-centered view of evolution and introduced the term meme. In 1982 he introduced an influential concept into evolutionary biology, presented in his book The Extended Phenotype, that the phenotypic effects of a gene are not necessarily limited to an organism's body, but can stretch far into the environment, including the bodies of other organisms.
Dawkins is an atheist, a vice president of the British Humanist Association, and a supporter of the Brights movement. He is well known for his criticism of creationism and intelligent design. In his 1986 book The Blind Watchmaker, he argued against the watchmaker analogy, an argument for the existence of a supernatural creator based upon the complexity of living organisms. Instead, he described evolutionary processes as analogous to a blind watchmaker. He has since written several popular science books, and makes regular television and radio appearances, predominantly discussing these topics. In his 2006 book The God Delusion, Dawkins contends that a supernatural creator almost certainly does not exist and that religious faith is a delusion—"a fixed false belief." As of January 2010 the English-language version has sold more than two million copies and had been translated into 31 languages.
Kent E. Hovind (born January 15, 1953) is an American young earth creationist. Hovind has spoken on creation science and has aimed to convince listeners to reject theories of evolution, geophysics, and cosmology in favor of the Genesis creation narrative from the Bible. Hovind's views are contradicted by scientific evidence and some of his ideas have also been criticized by young earth creationist organizations such as Answers in Genesis.
Hovind established the Creation Science Evangelism ministry in 1989, and frequently spoke on young Earth creationism at seminars at private schools and churches, debates, and on radio and television broadcasts. Since January 2007, Hovind has been serving a ten-year prison sentence after being convicted of 58 federal counts, including 12 tax offenses, one count of obstructing federal agents, and 45 counts of structuring cash transactions. He is incarcerated at the FPC Satellite Camp of the ADX Florence prison in Florence, Colorado.
On February 9, 1969, at the age of 16, Hovind became a born again Christian. In 1971, he graduated from East Peoria Community High School. He holds three degrees in Christian education (1974, 1988, 1991) from unaccredited institutions. He is married and has three adult children and five grandchildren. One of his sons, Eric Hovind, travels doing creationist presentations and debates using many of his father's arguments.
