Philosophical Perspectives on Reality: From Plato to Wittgenstein
Philosophical Perspectives on Reality
Plato: The World of Ideas
Plato’s philosophy is dualistic, positing two kinds of reality. One is the material world we perceive through our senses, which is subject to change. The other is the world of Forms or Ideas, accessible through reason, which are eternal and unchanging. According to Plato, true reality resides in the world of Ideas, which are abstract, eternal, and immutable. These Ideas are hierarchical, culminating in the ultimate Form, the Good.
Aristotle: Substance and Change
For Aristotle, the fundamental reality is substance. The question of reality translates into the question of the substance of things. Something has substance if it has a nature that is the cause of its own movement and evolution. This implies that reality is found in the particular things of sensory experience, unlike Plato’s view.
Thomas Aquinas: God and Creation
Thomas Aquinas combined Aristotelian principles with Christian faith. He proposed two essential principles to explain reality: 1) the need to postulate a creator God and 2) the need to combine Christian faith and reason to offer an explanation of reality consistent with Christian revelation.
Aquinas distinguishes between God and creatures based on the difference between existence and essence: 1) All created beings have essence but their existence is contingent. God’s existence, however, is a necessary part of His essence. 2) The existence of particular things comes from God’s action. Analyzing creatures requires seeking their creation, which entails considering God, whose essence includes existence. God is the only necessary being; all others are contingent.
Hegel: Reason and Spirit
Hegel’s system revolves around two key concepts:
- Reason: The supreme value of reality. Hegel believed that true reality is structured according to the demands of reason. Everything real is rational.
- Spirit: The product of reason and the new subject in Hegel’s philosophy. Reason is the most important feature of Spirit. When reason triumphs, it becomes integrated with human beings, allowing them to recognize themselves in everything that is real.
Critical Approaches to Reality
Kant: The Illusions of Reason
Kant sought to analyze the limits of reason and the foundations of knowledge. He argued that knowledge must be a combination of data from experience and the categories of understanding. Metaphysics, which relies solely on reason without empirical content, cannot provide certain knowledge. Metaphysical claims are illusions of reason, not genuine knowledge. Kant aimed to dethrone theoretical reason and acknowledge that some questions will always remain unanswered.
Marx: Materialism and Society
Marx believed that the fundamental reality is not reason or consciousness but matter. He argued that:
- Only matter exists.
- Matter is transformed through human labor.
- Human relations undergo historical development.
Marx analyzed reality and human beings through the lens of work and ownership, observing the increasing poverty of workers and the growing wealth of entrepreneurs.
Nietzsche: Life and Will to Power
Nietzsche viewed the history of metaphysics as a mistake that undervalues life and the senses. Embracing life leads to the emergence of a new human subject who rejects traditional moral codes, gods, and the pursuit of something beyond appearances. This “superman” recognizes the value of life and the power of their own will.
Wittgenstein: Language Analysis
Wittgenstein argued that philosophy should be reduced to the analysis of language, which is the fundamental human reality. We can only meaningfully deal with what we can express through language. For Wittgenstein, philosophy is an activity of logical analysis and clarification of thoughts. Its task is to clarify language to ensure adequate expression. Philosophical problems are ultimately language problems, and the only way to address them is through language analysis. There are two approaches to metaphysics: 1) Revisionist metaphysics, which critically reviews traditional philosophical problems and their meaning. 2) Descriptive metaphysics, which describes the conceptual limits of our language.
Science and Reality
Science offers a generally accepted image of reality. Reality is a philosophical concept that designates the common features of what is studied by metaphysics. The main objective of metaphysics is to understand what makes something exist as such. It studies “being” prior to the analysis of specific existing entities.
Reality and Illusion
Illusion is a false perception of the external world, linked to a wrong appearance that does not correspond to reality.
- Fact: There are real objects that we can see and touch.
- Virtual Reality: Things that lack material existence but are still part of our reality.
- Delusions, Hallucinations, and Wishful Thinking: These can be positive (wishful thinking) or negative (hallucinations). Both relate to reality as they are products of it.
