Introduction to Philosophy: Key Concepts and Thinkers
What is Human?
Humans have created culture, something no animal does. This cultural creation leads to questions about our existence and differentiates us from animals. This difference lies in the soul, a spiritual reality beyond nature. Underlying every form of thinking is a distinct form of human understanding.
Definitions
- Induction: Arriving at universal conclusions from particular observations.
- Deduction: Starting with universal principles and applying them to particular cases.
- Categorical Proposition: A proposition that affirms or denies a predicate of a subject.
- Categorical Syllogism: An argument where two terms are compared with a third term, leading to a conclusion joining or separating these terms.
- Extension of a Term: The number of objects to which a term relates.
- Compression of a Term: The characteristic properties of an object described by a term.
- Figure: The combination of the middle term in the premises of a syllogism.
- Instructions: Combinations of sentence types based on term extension and verb quality within a categorical syllogism.
- Inference: A conclusion drawn from two or more propositions.
Gottlob Frege (19th-20th Century)
This German philosopher and author of symbolic logic argued that logic, similar to mathematics, requires rigorous demonstration. He believed that logic is not merely a tool for mathematics but a critical component in analyzing the foundations of mathematics. According to Frege, this critical analysis is a part of logic itself.
Gottfried Wilhelm Leibniz (17th-18th Century)
A pioneer of symbolic logic, Leibniz believed that the ambiguity of ordinary language hindered philosophical progress. He sought to achieve the same certainty in philosophy as in mathematics. Leibniz envisioned pure logic and deductive calculation as formal operations independent of semantic content.
From Myth to Logos
Before philosophy, myths and magic addressed fundamental questions. Philosophy emerged as an attempt to answer these questions through rational thought.
Mythological Thinking
Myths poetically explain reality without verification. Natural phenomena are attributed to the arbitrary will of superior beings, passed down through tradition and imagination.
Logos (Rational Philosophical Thinking)
Logos posits that natural phenomena occur out of necessity, dictated by their nature. Explanations based on logos rely on reasoning, research, and logical arguments.
The Utility of Philosophy
- Thinking Well: Philosophy develops abstract thinking and the ability to work with theories.
- Understanding Reality: It encompasses all knowable things, including ourselves.
- Living Freely: Philosophy guides decision-making on important issues, enabling us to shape our destiny and be free.
Universality and Necessity
- Universal: Knowledge applicable to all, striving for objectivity. Mathematics exemplifies objective knowledge.
- Necessary: A consistent cause-and-effect relationship. Something necessary must always be so.
St. Anselm’s Ontological Argument
St. Anselm presented a rational, metaphysical argument for God’s existence. He argued that the very idea of God implies existence. God, being perfect, must possess all perfections, including existence. Denying God’s existence becomes a contradiction.
God’s Attributes
- Goodness
- Omniscience (all-knowing)
- Perfection
- Omnipresence (present everywhere)
From this perspective, evil does not exist. Anselm believed that denying God’s existence is self-defeating.
Questions of Philosophy: What Can I Expect?
Transcendence is a core human need, a belief in something higher. This need distinguishes humans from animals, evidenced by practices like burying the dead, which has roots in religious rituals. Atheism, a 19th-century concept, was once considered foolish. Kierkegaard noted that humans have invented the concept of God.
