Language, Truth, and Metaphysical Foundations

Language Theory: Wittgenstein and the Tractatus

Language is the problem of being tied to colloquial speech. The end of philosophy is knowledge; if it is not transmitted, language serves as an instrument of philosophy.

Theories of Language

• Naturalism: Word and truth are a single unit.
• Conventional Theory: Speech is prior to reality.
• Reflection: Language is a reflection of the mind.

Socrates rescued the concept from the Sophists, arguing that language is not merely nomos, but logos (action).

Categories of Knowledge

Knowledge has three degrees: sensitivity, understanding, and reason. To reach the third stage of self-knowledge, one must organize the mind through categories.

Features of Categories

• Architectural: How we know.
• Ontological: Defining the essence of reality.
• Liminal: We can only know what we can demonstrate; the limits of knowledge are defined by experience.

Aristotelian Categories

Essence, quantity, quality, relation, place, time, possession, action, condition, and passion.

Truth: Correspondence Between Thought and Reality

• Latin (Plato): Theory of reminiscence; learning is remembering.
• Hebrew: Truth comes from God; God grants us knowledge.
• Arabic (Al-Haq): Based on processes to achieve truth; the soul becomes a mirror of the divine.

Degrees of Truth

1. Ignorance
2. Doubt
3. Subjective certainty
4. Objective certainty

Criteria of Truth

• Authority: Someone says it is so.
• Tradition: It is true because it has always been so.
• Correspondence: Empirical verification that our view matches reality.
• Logical Consistency: The truth is valid if the speech is well-structured.
• Evidence: Truth without the need for further proof.
• Usefulness: Something is true when it functions within its context.

Historical Metaphysical Models

Metaphysics defines what is real through non-empirical means, creating expectations beyond the physical.

Presocratics

• Parmenides: Being is static.
• Heraclitus: Everything flows; perfection exists at the end of a cycle.

Plato

• The cave represents our condition.
• The shackles represent the senses.
• The sun represents the metaphysical realm.
