Knowledge and Truth: A Philosophical Inquiry
Theoretical and Practical Reason
Theoretical reason focuses on contemplating the world, seeking to decipher, explain, and understand reality without direct intervention. Practical reason, according to Kant, guides action, opposing passions and directing us towards moral ideals.
Awareness
- Opinion: A belief held without complete certainty.
- Belief: A conviction held with subjective certainty, but lacking objective justification.
- Knowledge: A belief supported by both subjective certainty and objective justification.
Interests of Knowledge
According to Kant
- Theoretical: Achieving perfect knowledge of nature.
- Practical: Understanding what we can do and expect if we act morally, leading to knowledge about liberty, ethics, and religion.
According to Apel and Habermas
- Technical: Dominating and exploiting nature, guiding empirical sciences.
- Practical: Fostering communication and understanding among beings.
- Liberating: Freeing humans from domination and repression, leading to critical social science.
Possibilities of Knowledge
- Dogmatism: Naive confidence in the capacity of our cognitive faculties.
- Skepticism: The belief that reliable knowledge is unattainable due to insufficient justification.
- Subjectivism and Relativism: The view that truth is dependent on the individual subject (subjectivism) or culture and social group (relativism).
- Pragmatism: Equating truth with usefulness.
- Criticism: A middle ground between dogmatism and skepticism, acknowledging the possibility of knowledge while recognizing its limitations.
- Perspectivism: Knowledge of reality is attainable by combining different perspectives.
Explanatory Models
- Realism (Aristotle): Reality exists independently of the subject.
- Idealism: Reality is dependent on the knowing subject.
- Hermeneutics: Understanding human actions and history by interpreting events in their unique context.
States of Truth
- Ignorance: Admitting lack of knowledge about a specific matter.
- Doubt: Inability to affirm or deny truth due to balanced reasons for and against.
- Subjective Certainty: Claiming truth without admitting any possibility of error.
Criteria of Truth
- Authority: Accepting a statement based on the credibility of the source.
- Tradition: Accepting something as true due to its long-term acceptance.
- Correspondence: Agreement between thought and empirical reality.
- Logical Consistency: Absence of contradictions within a system of statements.
- Utility: Truth is what is beneficial and useful.
- Evidence: Indisputable, intuitively true statements, often requiring demonstration through reasoning.
Theories of Truth
- Coherence Theory: Truth depends on the consistency of a proposition within a set of propositions.
- Pragmatist Theory (William James): Truth is defined by its utility in problem-solving and its beneficial impact.
