Philosophical Perspectives on the Self and Divinity

Theories of the Self and Personal Identity

Substance Theory – René Descartes

Substance theory argues that the self is a single, unified, and unchanging entity that persists over time. According to Descartes, the self is not physical but a mental substance that controls the body and mind, much like a captain steering a ship. This means that even though our experiences and surroundings change, the core “self” remains the same. The self is indivisible and cannot be broken down into parts or altered by experience. For example, a person is still the same individual from childhood to adulthood, even though their appearance, thoughts, and life circumstances have changed.

Bundle Theory – David Hume

Bundle theory claims that the self is not a single, stable entity, but rather a collection of changing perceptions and experiences. Hume argued that when he looked inward, he could not find a fixed “self,” only fleeting thoughts, sensations, and memories. These experiences are constantly changing, and there is no underlying unity holding them together. As a result, the self is simply a bundle of impressions that are loosely connected over time. For example, a person might feel happy in the morning, stressed in the afternoon, and excited at night, showing there is no single constant “self,” just changing experiences.

Narrative Theory – Paul Ricoeur

Narrative theory suggests that the self is created through the stories we tell about our lives. According to Ricoeur, people make sense of their experiences by organizing them into a narrative that connects their past, present, and future. This story gives the self a sense of unity and identity, even though individual experiences may change. We are both the main character and the author of our own life story, shaping it as we go. For example, someone might describe themselves as “a hardworking student who overcame challenges,” using their past experiences to form a meaningful life story.

Project Theory – Jean-Paul Sartre

Project theory views the self as something that is constantly being created through our choices and actions. Sartre argued that the self is not a fixed thing or even a bundle, but an ongoing, future-oriented project. It is always under construction, shaped by decisions, desires, and experiences over time. The self is never complete and continues to evolve as long as a person lives. For example, a student who decides to study hard, choose a career path, and set future goals is actively shaping who they will become.

Core Concepts of Human Nature

• Essentialism: The view that reason is the distinguishing feature of human beings and that each person has an essential, defining nature that makes them uniquely human.
• Egoism: Acting in a way that promotes our own interests.
• Altruism: The unselfish concern for the well-being of other people.

Arguments Regarding the Existence of God

The Ontological Argument (St. Anselm)

This argument claims that God’s existence can be proven through logic and the definition of God rather than through physical evidence. St. Anselm argued that God is “the greatest being that can be conceived,” and a being that exists is greater than one that only exists as an idea. Therefore, if God is the greatest possible being, God must exist. Critics challenge this argument by saying that imagining something does not prove that it exists and that the argument assumes God’s existence before proving it.

The Cosmological Argument (St. Thomas Aquinas)

This theory argues that the existence of the universe requires a first cause. Aquinas believed that everything that begins to exist must have a cause, and because there cannot be an endless chain of causes, there must be a first cause that started everything. He called this the “first mover” or “unmoved mover,” which he identified as God. Critics question why this first cause must be God and argue that there may be another explanation for the universe’s existence.

The Big Bang Argument

This perspective connects modern science with the question of God’s existence. Since the Big Bang suggests that the universe had a beginning, some philosophers argue that something beyond the universe must have caused it to exist. This cause would need to exist outside time and space, which some believe matches the idea of God. However, critics argue that the Big Bang does not prove God because the cause of the universe could be something unknown or a natural explanation.

The Teleological or Design Argument (William Paley)

The design argument suggests that the complexity and order of the universe indicate the existence of a designer. William Paley compared the universe to a watch, arguing that just as a watch’s complex design requires a watchmaker, the complexity of nature requires a creator. Supporters believe that life and the universe appear too organized to happen by chance. However, Charles Darwin’s theory of evolution challenged this argument by explaining that complexity can develop through natural selection without needing a designer.

The Fine-Tuning Argument

This theory claims that the universe appears to have extremely precise conditions that allow life to exist. The laws of nature, such as gravity and physical constants, seem carefully balanced, leading some philosophers to argue that this suggests a creator or intelligent designer. Critics respond that fine-tuning does not necessarily prove God and that the universe’s conditions may have natural explanations that are not yet fully understood.

The Moral Argument (Immanuel Kant)

This states that the existence of morality points toward the existence of God. Immanuel Kant argued that humans believe good should ultimately be rewarded and evil should be punished, but this does not always happen in the world. Therefore, there must be a higher power capable of creating ultimate justice. Critics argue that morality can exist without God and that humans can believe in right and wrong without requiring a divine source.

The Problem of Evil

The problem of evil challenges God’s existence by questioning how suffering can exist in a world created by an all-powerful and perfectly good God. If God is able to prevent suffering and wants to eliminate evil, why does evil still exist? Critics argue that this creates a contradiction for belief in God. In response, some believers argue that suffering may exist because of human free will, moral growth, or purposes beyond human understanding.

Influential Philosophers and Their Teachings

Socrates

A Greek philosopher known for asking questions and encouraging people to think critically. He developed the Socratic Method, which involves asking a series of questions to help people discover answers themselves. He challenged people’s beliefs and exposed weaknesses in their arguments, believing true wisdom comes from recognizing your own ignorance (“I know that I know nothing”). He taught that knowledge equals virtue (people do good when they understand what is right) and that evil comes from ignorance. He did not write books, but his ideas were recorded by students like Plato. Criticized by Athenian society, he was accused of not respecting the gods and corrupting the youth; he was sentenced to death and chose to drink hemlock rather than abandon his beliefs.

Plato

A student of Socrates and founder of the Academy in Athens. He wrote many dialogues featuring Socrates and believed in the Theory of Forms: the physical world is imperfect, while true reality exists in a world of perfect “Forms” or ideas. In The Republic, he described an ideal society governed by a small group of intelligent, educated guardians. He opposed democracy, believing uneducated people could make poor decisions. His proposed school system involved regular testing, where those who excelled would eventually join the guardian class. He also proposed the tripartite soul consisting of reason, spirit, and appetite, where reason should rule to control desires and emotions. He believed the purpose of human life is to seek truth, justice, and the highest good.

Aristotle

The father of natural sciences and a student of Plato, Aristotle founded the Lyceum. He believed knowledge comes from observation, experience, and reason rather than the “pleasure of the gods.” He argued that the goal of life is eudaimonia (human flourishing) achieved through practicing virtue. He created the Golden Mean, the idea that virtue is the balance between extremes (e.g., courage is the mean between cowardice and recklessness). He viewed humans as rational and social animals and believed the best government should aim for the common good.

Thomas Hobbes

Hobbes believed humans are naturally self-interested and motivated by survival. In his book Leviathan, he presented a negative view of humanity, describing life in a state of nature as “solitary, poor, nasty, brutish, and short.” He argued that people are aggressive and competitive, and because everyone acts only to satisfy personal desires, society and government are necessary to maintain order.

Xunzi and Mengzi

Xunzi believed humans are naturally selfish and driven by desires, arguing that morality is achieved only through education, discipline, and social rules. Conversely, Mengzi believed human nature is inherently good, much like water naturally flows downward. He argued that humans have an innate sense of right and wrong and a natural sympathy for those in distress. To Mengzi, people do evil only when their good nature is not nourished or educated.

Charles Darwin

Darwin viewed humans as animals shaped by evolution and natural selection. He argued that human purpose is not predetermined but is instead connected to the biological imperatives of adapting, surviving, and reproducing.

St. Thomas Aquinas

Aquinas believed humans were created by God with reason and a moral purpose. He argued that the goal of life (telos) is to live according to natural law and ultimately to know and serve God.

Jean-Paul Sartre

Sartre championed the concept that “existence precedes essence,” meaning humans have no fixed purpose or predetermined nature. Instead, people create their own meaning through choices and actions. He argued that humans define themselves and are “condemned” to be free, having no choice but to make their own decisions.
