Existence of God

The question of whether God exists is a central debate in theology and the philosophy of religion. This subject involves several complex academic disciplines. It touches on epistemology, which is the study of the nature and scope of knowledge. It also involves ontology, the study of the nature of being or existence. Furthermore, it relates to the theory of value, especially since some definitions of God include perfection. Philosophers use various methods to explore this question. These include logical, empirical, metaphysical, subjective, and scientific arguments.

Philosophical positions on this topic are organized along different axes. Theism is the proposition that God exists. Atheism is the proposition that God does not exist. Some people hold positions regarding knowledge rather than belief. Gnosticism and agnosticism deal with whether one can actually know the truth. Other views focus on different aspects of the debate. Ignosticism looks at whether the concept of God is even coherent. Apatheism concerns whether the existence of God has any practical importance to human life. Richard Dawkins described a spectrum of probability for these views. This spectrum ranges from a strong theist, who has 100% probability, to a strong atheist, who knows there is no God.

History shows that many thinkers have shaped this discussion. The Western tradition began with Plato and Aristotle. They proposed a being responsible for fashioning the universe. This being was called the demiurge or the unmoved mover. These are types of cosmological arguments. Later, St. Anselm formulated the first ontological argument. Thomas Aquinas presented his own version of the cosmological argument, known as the first way. René Descartes argued that a benevolent God is logically necessary for sensory evidence to be meaningful. John Calvin proposed the idea of a sensus divinitatis, a natural knowledge of God within humans.

Islamic philosophers also contributed significant arguments to this field. Averroes developed ideas influenced by Aristotle's unmoved mover. Al-Ghazali and Al-Kindi presented the Kalam cosmological argument. Avicenna offered the Proof of the Truthful, while Al-Farabi used Neoplatonic arguments. The 12th-century scholar Ibn Rushd used the concept of providence and invention. He argued that the Earth's weather patterns are finely tuned to support human life. He believed the Sun and Moon serve human needs rather than being random objects.

This suggests a higher being acted as a fine tuner for the world.

Jewish scholar Maimonides also used logic to address the divine. He did not start by defining what God is. Instead, he used the description of the universe to find proofs. He observed that heavenly bodies are committed to eternal motion. Maimonides argued that every physical object is finite. A finite object can only contain a finite amount of power. Therefore, he concluded there must be an infinite power to drive the motion of the universe. He believed this infinite being is neither a body nor a force within a body.

There are many ways to define the nature of God. In classical theism, God is the metaphysically ultimate being. This being is described as timeless, simple, and sovereign. Classical theists believe God cannot be completely defined by humans. They argue that a transcendent nature cannot be captured by mere human definitions. Other views offer different relationships between God and the universe. Pantheism suggests that God and the universe are the same thing. Deism and panentheism suggest a God that is distinct from or extends beyond the universe.

These views often deny that God intervenes in the world.

Modern data provides a look at how many people hold these beliefs. A 2020 PhilPapers survey showed different results for different groups. Among philosophers of religion, 69.50% accept or lean towards theism. In that same group, 19.86% accept or lean towards atheism. However, philosophers as a whole are more skeptical. The survey found that 66.72% of all philosophers leaned towards atheism. Only 18.64% of all philosophers leaned towards theism.

These numbers show that the debate is still very active in academia.

Different schools of thought also use different methods to argue their points. Thomas Aquinas distinguished between preambles of faith and articles of faith. Preambles are truths that can be demonstrated by reason, such as the existence of God. Articles of faith are truths that cannot be reached by reason alone. Another approach is called presuppositional apologetics. This school was instituted by Cornelius Van Til in the late 1920s. Presuppositionalists deny that there is common ground between believers and non-believers. They argue that belief in God is a necessary condition for human experience to make sense.
