John Andrew Leslie (born 2 August 1940) is a Canadian philosopher and writer.
Leslie was educated at Wadham College, Oxford, earning his B.A. in English Literature in 1962 and his M.Litt. in Classics in 1968. He is currently Professor emeritus at the University of Guelph, in Ontario, Canada.
In his book Universes, Leslie describes a philosophical parable in which an individual survives a firing squad of fifty expert marksmen unscathed. He offers two explanations for this remarkable event: either it is a fortuitous outcome, to be expected occasionally by pure chance among many thousands of attempted executions by firing squad; or it is intentional. Francis Collins references this parable in his book The Language of God: A Scientist Presents Evidence for Belief as part of his argument that the Anthropic Principle strongly suggests a Creator with intent.
Leslie has spoken as follows about his life's work:
What I have to contribute is some technical defense of the idea that if you had an infinitely rich [universe], it could be explained by reference to its value. Its goodness could be the creative force which had produced it. I think if I would like to be remembered as a philosopher for any one thing, that would be the thing I'd most like to be remembered for.
Leslie is a pantheist. [1] [2] His philosophical work takes influence from David Lewis, Plato and Spinoza. [1] [3]
In his book Infinite Minds: A Philosophical Cosmology (2001), Leslie argues for a pantheistic universe in which everything exists in a divine mind. Philosopher Brendan Sweetman commented that the book promotes a "highly speculative, pantheistic theory that is fascinating in its own way, but that will probably convince very few." [1] Leslie's book is unique because he accepts and uses arguments for the existence of God which are usually used to support theism such as a version of the cosmological argument and the design argument based on fine-tuning, but he explains these in a pantheistic way. [4]
Pantheism is the philosophical religious belief that reality, the universe and the cosmos are identical to divinity and a supreme being or entity. The physical universe is thus understood as an immanent deity, still expanding and creating, which has existed since the beginning of time. The term 'pantheist' designates one who holds both that everything constitutes a unity and that this unity is divine, consisting of an all-encompassing, manifested god or goddess. All astronomical objects are thence viewed as parts of a sole deity.
Panentheism is the belief that the divine intersects every part of the universe and also extends beyond space and time. The term was coined by the German philosopher Karl Krause in 1828 to distinguish the ideas of Georg Wilhelm Friedrich Hegel (1770–1831) and Friedrich Wilhelm Joseph Schelling (1775–1854) about the relation of God and the universe from the supposed pantheism of Baruch Spinoza, after reviewing Hindu scriptures. Unlike pantheism, which holds that the divine and the universe are identical, panentheism maintains an ontological distinction between the divine and the non-divine and the significance of both.
Theism is broadly defined as the belief in the existence of at least one deity. In common parlance, or when contrasted with deism, the term often describes the classical conception of God that is found in monotheism — or gods found in polytheistic religions — a belief in God or in gods without the rejection of revelation as is characteristic of deism. Gnosticism is the belief in personal spiritual knowledge.
An argument from nonbelief is a philosophical argument that asserts an inconsistency between the existence of God and a world in which people fail to recognize him. It is similar to the classic argument from evil in affirming an inconsistency between the world that exists and the world that would exist if God had certain desires combined with the power to see them through.
John Leslie Mackie was an Australian philosopher. He made significant contributions to the philosophy of religion, metaphysics, and the philosophy of language.
Richard Granville Swinburne is an English philosopher. He is an Emeritus Professor of Philosophy at the University of Oxford. Over the last 50 years Swinburne has been a proponent of philosophical arguments for the existence of God. His philosophical contributions are primarily in the philosophy of religion and philosophy of science. He aroused much discussion with his early work in the philosophy of religion, a trilogy of books consisting of The Coherence of Theism, The Existence of God, and Faith and Reason.
William Lane Craig is an American analytic philosopher, Christian apologist, author, and Wesleyan theologian who upholds the view of Molinism and neo-Apollinarianism. He is currently a Professor of Philosophy at Houston Baptist University and a Research Professor of Philosophy at Biola University's Talbot School of Theology. Craig has updated and defended the Kalam cosmological argument for the existence of God. He has also published work where he argues in favor of the historical plausibility of the resurrection of Jesus. His study of divine aseity and Platonism culminated with his book God Over All.
Naturalistic pantheism, also known as scientific pantheism, is a form of pantheism. It has been used in various ways such as to relate God or divinity with concrete things, determinism, or the substance of the universe. God, from these perspectives, is seen as the aggregate of all unified natural phenomena. The phrase has often been associated with the philosophy of Baruch Spinoza, although academics differ on how it is used.
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.
The Kalam cosmological argument is a modern formulation of the cosmological argument for the existence of God. It is named after the Kalam from which its key ideas originated. William Lane Craig was principally responsible for giving new life to the argument, due to his The Kalām Cosmological Argument (1979), among other writings.
Dialogues Concerning Natural Religion is a philosophical work by the Scottish philosopher David Hume, first published in 1779. Through dialogue, three philosophers named Demea, Philo, and Cleanthes debate the nature of God's existence. Whether or not these names reference specific philosophers, ancient or otherwise, remains a topic of scholarly dispute. While all three agree that a god exists, they differ sharply in opinion on God's nature or attributes and how, or if, humankind can come to knowledge of a deity.
In monotheistic thought, God is usually viewed as the supreme being, creator, and principal object of faith. In polytheistic thought, a god is "a spirit or being believed to control some part of the universe or life and often worshipped for doing so, or something that represents this spirit or being". Belief in the existence of at least one god is called theism.
The following outline is provided as an overview of and topical guide to metaphysics:
Philosophical theism is the belief that the Supreme Being exists independent of the teaching or revelation of any particular religion. It represents belief in God entirely without doctrine, except for that which can be discerned by reason and the contemplation of natural laws. Some philosophical theists are persuaded of God's existence by philosophical arguments, while others consider themselves to have a religious faith that need not be, or could not be, supported by rational argument.
Articles related to philosophy of religion include:
Skeptical theism is the view that people should remain skeptical of their ability to discern whether their perceptions about evil can be considered good evidence against the existence of the orthodox Christian God. The central thesis of skeptical theism is that it would not be surprising for an infinitely intelligent and knowledgeable being's reasons for permitting evils to be beyond human comprehension. That is, what may seem like pointless evils may be necessary for a greater good or to prevent equal or even greater evils. This central thesis may be argued from a theistic perspective, but is also argued to defend positions of agnosticism.
The belief that God became the Universe is a theological doctrine that has been developed several times historically, and holds that the creator of the universe actually became the universe. Historically, for versions of this theory where God has ceased to exist or to act as a separate and conscious entity, some have used the term pandeism, which combines aspects of pantheism and deism, to refer to such a theology. A similar concept is panentheism, which has the creator become the universe only in part, but remain in some other part transcendent to it, as well. Hindu texts like the Mandukya Upanishad speak of the undivided one which became the universe.
Jordan Howard Sobel was a Canadian-American philosopher specializing in ethics, logic, and decision theory. He was a professor of philosophy at the University of Toronto, Canada. In addition to his areas of specialization, Sobel made notable contributions in the fields of philosophy of religion, and value theory. Before his death, Sobel was considered by Christian apologist William Lane Craig to be the leading philosophical defender of Atheism prior to Graham Oppy.
Theistic finitism, also known as finitistic theism or finite godism, is the belief in a deity that is limited. It has been proposed by some philosophers and theologians to solve the problem of evil. Most finitists accept the absolute goodness of God but reject omnipotence.
