Appearance and Reality in Metaphysics

The distinction between appearance and reality is the origin of metaphysics. Appearance is that which is captured by the senses and often does not correspond to what really is, which can only be grasped by reason. The senses capture the look of things, while reason captures the essence behind them.

Defining Truth: Ontic and Epistemological

Ontic Truth

Ontic truth occurs when something truly is what it appears to be. Truth and authenticity are understood as the opposite of inauthenticity.

Epistemological Truth

Epistemological truth is not about the things themselves, but about the knowledge we have of those things. It is considered true when what you say agrees with or corresponds to the facts.

Descartes: A Transition to Modern Philosophy

Descartes lived during the Renaissance, a period of transition between medieval and modern philosophy. Key features of this era include:

• Decomposition of feudalism: The emergence of a new class-based society.
• Loss of medieval religious meaning: A shift from theocentrism to anthropocentrism, with the rise of national monarchies.
• Secular spirit: Civil power and politicians distanced themselves from the Church.
• Discoveries: New geographical and scientific discoveries expanded the known world.
• Reformation: The breakdown of religious unity.
• The new science: A focus on mathematizing the observable world.
• Everything: The problem of actually going into the background.

Rationalism in the 17th and 18th Centuries

Rationalism...

Social by Nature

Human beings are social by nature. This position, represented by Aristotle, posits that humans are "political animals" who are inherently sociable. We need to live in society and culture to develop according to our abilities. Since society precedes the individual, it is essential for satisfying our needs. Only within a society can humans achieve perfection and happiness; therefore, living in society is a requirement of human nature.

For Aristotle, society is unique to humans because we are endowed with reason to distinguish between good and evil and possess language to express ourselves. Man is the only creature with a moral nature.

Conversely, some argue that living in society is not a requirement of nature, but rather an artificial...

Understanding Empiricism

Empiricism is the philosophical theory according to which the origin and limits of knowledge are sensory experience. The best-known empiricists include Thomas Hobbes, John Locke, David Hume, and George Berkeley.

Understanding Rationalism

Conversely, Rationalism is the philosophical doctrine that recognizes no source of knowledge other than reason, thus rejecting revelation, faith, and the senses. In the history of philosophy, rationalism has a more limited meaning, beginning in the 17th century with the figure of the mathematician René Descartes.

Key Differences Between Empiricism and Rationalism

It is interesting to compare Empiricism and Rationalism through their core tenets:

Descartes, Rationalism, and the Enlightenment

René Descartes' philosophy significantly influenced the course of thought, paving the way for the 17th-century Enlightenment. The freedoms proclaimed during the Enlightenment—such as the autonomy of reason over the weight of authority and religious dogmatism in fields from politics to science—can be considered progress that contributes to our freedoms today.

The Mathematization of Reality

Regarding mathematization and scientific-technical development, Descartes proposed a method heavily influenced by mathematics. Contemporary Western science often continues under the premise that reality is mathematicizable. Knowing things involves quantifying them, and the mathematical model remains central to...

Augustine's Inner Search

Augustine is a major figure in Christian philosophy. He believed that God is the source of all reality, truth, and goodness. For Augustine, the search for God begins with self-examination. He believed that God knows us from within, and the soul, as an image of God, is the starting point for this quest. Augustine rejected the Platonic idea of finding truth in the external world, instead advocating for an inner quest to analyze the contents of consciousness.

Faith and Reason in Augustine's Thought

Some Christian philosophers believed that faith lies beyond human capabilities and rejected reason's interference. Augustine, however, saw faith and reason as complementary. He believed that God gave us reason and that religion...

Asymmetry Between Hypothesis Justification and Refutation

Arguments used to justify and refute a hypothesis ($H$) often appear symmetrical. Both typically involve two conditions and an experiment resulting from the premises. However, this symmetry is broken when the argument for justification further demands that Condition 1 be fulfilled.

The reason for this asymmetry is crucial: arguments of type (**) — refutation — are all deductively valid. In contrast, arguments of type (*) — explanation — are only inductively valid, meaning the conclusion is only probable.

We can find counterexamples: cases of the form (*) — justification — where the truth of the premises does not make the conclusion highly probable. That is, the hypothesis might...

Descartes' Fourth Meditation: The Nature of Knowledge

Distinguishing Knowledge and Certainty

In the Fourth Meditation, Descartes seeks to define the nature of human knowledge. He establishes a distinction between the knowledge of res extensa (extended things) and the absolute certainty we possess regarding the self and God, specifically through innate ideas such as the concept of perfection.

The Existence of a Perfect God

Descartes argues that God is perfect and omniscient. The very act of hesitation and doubt serves as the primary argument for the existence of the self. Because God is perfect and I am imperfect and dependent, it follows that I was created by a higher power.

Truth, Deception, and Moral Perfection

A lie implies a lack of truth, which...

Understanding Metaphysics

Reason faces issues it is incapable of solving, themes that have emerged for humanity and have never received a response. These unresolved questions form the core of metaphysical thought. Metaphysics rationally and conceptually provides the essence of what exists beyond the information gained through the senses, that is, a priori.

Reason itself provides basic knowledge and decides which ones are true. Its purpose is to achieve perfect knowledge of everything.

Metaphysics is also responsible for any mental speculation that goes beyond sensory and spiritual reality. It deals with essences, first and final causes, and the necessary relationships in all that exists. It also influences moral issues dogmatically.
