John Leslie (Philosopher)

John Leslie (born 1940) is a Canadian philosopher known primarily for his work in metaphysics, philosophy of religion, and cosmology. He is considered a significant figure in contemporary discussion of the anthropic principle and related concepts.

His key ideas include:

• <a href="https://www.wikiwhat.page/kavramlar/Anthropic%20Principle">Anthropic Principle</a>: Leslie is a strong advocate of the Anthropic Principle, particularly the idea that the universe must have properties that allow for the existence of observers, such as ourselves. He explores different versions of the principle, arguing for its importance in understanding the fine-tuning of the universe's physical constants.

• <a href="https://www.wikiwhat.page/kavramlar/Ultimate%20Explanation">Ultimate Explanation</a>: Leslie seeks to identify what might serve as an ultimate explanation for the universe's existence and its remarkable fine-tuning. He considers several possibilities, including divine creation, the Many-Worlds Interpretation of quantum mechanics, and a self-selecting universe.

• <a href="https://www.wikiwhat.page/kavramlar/Fine-Tuning">Fine-Tuning</a>: He argues that the laws and constants of nature appear to be finely-tuned to allow for the emergence of life. This fine-tuning is often presented as evidence for intelligent design or a multiverse.

• <a href="https://www.wikiwhat.page/kavramlar/Ontological%20Argument">Ontological Argument</a>: Leslie has also contributed to discussions of the Ontological Argument for the existence of God.

His notable books include Value and Existence (1979), Universes (1989), and Infinite Minds: A Philosophical Cosmology (2001). Leslie's work has had a significant impact on discussions surrounding the intersection of science, philosophy, and religion.
