The anthropic principle, also known as the "observation selection effect", is the hypothesis, first proposed in 1957 by Robert Dicke, that the range of possible observations that could be made about the universe is limited by the fact that observations could happen only in a universe capable of developing intelligent life. Proponents of the anthropic principle argue that it explains why the universe has the age and the fundamental physical constants necessary to accommodate conscious life, since if either had been different, no one would have been around to make observations. Anthropic reasoning is often used to deal with the idea that the universe seems to be finely tuned for the existence of life.
Intelligent design (ID) is a pseudoscientific argument for the existence of God, presented by its proponents as "an evidence-based scientific theory about life's origins". Proponents claim that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection." ID is a form of creationism that lacks empirical support and offers no testable or tenable hypotheses, and is therefore not science. The leading proponents of ID are associated with the Discovery Institute, a Christian, politically conservative think tank based in the United States.
The teleological argument is an argument for the existence of God or, more generally, that complex functionality in the natural world which looks designed is evidence of an intelligent creator.
The characterization of the universe as finely tuned suggests that the occurrence of life in the universe is very sensitive to the values of certain fundamental physical constants and that values different from the observed ones are more probable. If the values of any of certain free parameters in contemporary physical theories had differed only slightly from those observed, the evolution of the universe would have proceeded very differently, and "life as we know it" might not have been possible.
The existence of God is a subject of debate in theology, philosophy of religion and popular culture. A wide variety of arguments for and against the existence of God or deities can be categorized as logical, empirical, metaphysical, subjective or scientific. In philosophical terms, the question of the existence of God or deities involves the disciplines of epistemology and ontology and the theory of value.
Internet Infidels, Inc. is a Colorado Springs, Colorado-based nonprofit educational organization founded in 1995 by Jeffery Jay Lowder and Brett Lemoine. Its mission is to use the Internet to promote a view that supernatural forces or entities do not exist. Internet Infidels maintains a website of educational resources about agnosticism, atheism, freethought, humanism, secularism, and other nontheistic viewpoints particularly relevant to nonbelievers and skeptics of the paranormal. Relevant resources include rebuttals to arguments made by religious apologists and theistic philosophers, transcripts of debates between believers and nonbelievers, and responses from opponents of a naturalistic worldview. The site has been referred to by one of its critics, Christian apologist Gary Habermas, as "one of the Internet's main Web sites for skeptics", and by skeptical physicist Taner Edis as "a major Web site serving nonbelievers". Its tagline is "a drop of reason in a pool of confusion".
Theistic science, also referred to as theistic realism, is the pseudoscientific proposal that the central scientific method of requiring testability, known as methodological naturalism, should be replaced by a philosophy of science that allows occasional supernatural explanations which are inherently untestable. Proponents propose supernatural explanations for topics raised by their theology, in particular evolution.
An intelligent designer, also referred to as an intelligent agent, is the pseudoscientific hypothetical willed and self-aware entity that the intelligent design movement argues had some role in the origin and/or development of life. The term "intelligent cause" is also used, implying their teleological supposition of direction and purpose in features of the universe and of living things.
Russell's teapot is an analogy, formulated by the philosopher Bertrand Russell (1872–1970), to illustrate that the philosophic burden of proof lies upon a person making empirically unfalsifiable claims, as opposed to shifting the burden of disproof to others.
Metaphysical naturalism is a philosophical worldview which holds that there is nothing but natural elements, principles, and relations of the kind studied by the natural sciences. Methodological naturalism is a philosophical basis for science, for which metaphysical naturalism provides only one possible ontological foundation. Broadly, the corresponding theological perspective is religious naturalism or spiritual naturalism. More specifically, metaphysical naturalism rejects the supernatural concepts and explanations that are part of many religions.
The Ultimate Boeing 747 gambit is a counter-argument to modern versions of the argument from design for the existence of God. It was introduced by Richard Dawkins in chapter 4 of his 2006 book The God Delusion, "Why there almost certainly is no God".
Victor John Stenger was an American particle physicist, philosopher, author, and religious skeptic.
The argument from reason is an argument against metaphysical naturalism and for the existence of God. The best-known defender of the argument is C. S. Lewis. Lewis first defended the argument at length in his 1947 book, Miracles: A Preliminary Study. In the second edition of Miracles (1960), Lewis substantially revised and expanded the argument.
Why Darwin Matters: The Case Against Intelligent Design is a 2006 book by Michael Shermer, an author, publisher, and historian of science. Shermer examines the theory of evolution and the arguments presented against it. He demonstrates that the theory is very robust and is based on a convergence of evidence from a number of different branches of science. The attacks against it are, for the most part, very simplistic and easily demolished. He discusses how evolution and other branches of science can coexist with religious beliefs. He describes how he and Darwin both started out as creationists and how their thinking changed over time. He examines current attitudes towards evolution and science in general. He finds that in many cases the problem people have is not with the facts about evolution but with their ideas of what it implies.
The term New Atheism was coined by the American journalist Gary Wolf in 2006 to describe the positions of some atheist academics, writers, scientists, and philosophers of the 21st century. New Atheism advocates the view that superstition, religion, and irrationalism should not simply be tolerated. Instead, they should be criticised, countered, examined, and challenged by rational argument, especially when they exert strong influence on the broader society, such as in government, education, and politics. Major figures of New Atheism include Richard Dawkins, Sam Harris, Christopher Hitchens and Daniel Dennett, collectively referred to as the "four horsemen" of the movement, as well as Ayaan Hirsi Ali until her conversion to Christianity in 2023.
The Grand Design is a popular-science book written by physicists Stephen Hawking and Leonard Mlodinow and published by Bantam Books in 2010. The book examines the history of scientific knowledge about the universe and explains eleven-dimensional M-theory. The authors of the book point out that a Unified Field Theory may not exist.
The relationship between intelligent design and science has been a contentious one. Intelligent design (ID) is presented by its proponents as science and claims to offer an alternative to evolution. The Discovery Institute, a politically conservative think tank and the leading proponent of intelligent design, launched a campaign entitled "Teach the Controversy", which claims that a controversy exists within the scientific community over evolution. The scientific community rejects intelligent design as a form of creationism, and the basic facts of evolution are not a matter of controversy in science.
In philosophy, naturalism is the idea that only natural laws and forces operate in the universe. In its primary sense it is also known as ontological naturalism, metaphysical naturalism, pure naturalism, philosophical naturalism and antisupernaturalism. "Ontological" refers to ontology, the philosophical study of what exists. Philosophers often treat naturalism as equivalent to materialism.
Taner Edis is a Turkish American physicist and skeptic. He is a professor of physics at Truman State University. He received his B.S. from Boğaziçi University in Turkey and his M.A. and Ph.D. from Johns Hopkins University. Edis is the author of several books on creationism, religion and science. He is a scientific and technical consultant for the Committee for Skeptical Inquiry.
