Truth and Knowledge: Theories and Models
Truth and Knowledge
Options for Acquiring Knowledge
The goal of knowledge is to understand things or the state of receiving the adoption of the end. Two elements are shared with others: the subject (the activity of knowledge) and the object (assuming the owner). One end to the other two: knowledge (the activity of knowledge, the search for truth) and knowledge (the result of finding the truth).
Arising from the highest issues of knowledge, the question of whether knowledge is possible can be answered in six ways:
- Dogmatism: The belief that certain people possess the capability for knowledge. Our cognitive capabilities are deemed sufficient.
- Skepticism: The belief that it is impossible to acquire reliable knowledge, as there is never enough evidence to consider something true.
- Subjectivism and Relativism: The belief that universally valid truths do not exist. In subjectivism, what is true depends on each individual. In relativism, something is considered true or false based on the culture or the time of each group.
- Pragmatism: Matches what is accurate and useful.
- Criticism: An attitude between dogmatism and skepticism. True knowledge can be obtained, but it requires making an effort to clarify the extent of our knowledge and critically checking reality. There are two types of criticism:
- Kantian Criticism: Suggested by Immanuel Kant.
- Critical Rationalism: Represented by Karl Popper and Hans Albert, it suggests that all knowledge is fallible and subject to testing.
- Perspectivism: Suggested by Jose Ortega y Gasset, it proposes that reality can be viewed from different perspectives, and each generation’s perspective joins the truth. Each new historical view of reality is particularly aware of this.
Models of Knowledge Change
- Realism (Aristotle): The object has priority. Things are considered matters of direct knowledge, and the subject has a receptive attitude. The real is understandable in itself (things will be known as they are). This is a characteristic of natural behavior (trust in the elements of knowledge).
- Idealism (Kant to Hegel): The subject has priority. It questions whether the world is meaningless. Ideas are products of direct knowledge, and the subject has a constructive position. The real is understood based on the subject, representing an artificial attitude (critical knowledge).
- Phenomenology: Aims to understand things through the appearance of consciousness, combining idealism and realism.
- Hermeneutics: Closely related to phenomenology, it emphasizes that understanding is based on prejudice; there are no empty events.
Theories of Truth
Throughout history, various sessions have sought to define, explain, and understand truth. Each of these is based on a theory of truth. Four of the most relevant are:
- Truth as Correspondence: This is the most basic theory. Aristotle’s classical definition states: “To say of what is that it is not, or of what is not that it is, is false, while to say of what is that it is, and of what is not that it is not, is true.” The elements involved are:
- The object (what is)
- The statement (the subject and the representation of the object) Truth is a matching relationship between these two, a correspondence or appropriateness, as indicated by Ludwig Wittgenstein.
- Truth as Coherence: Hegel first proposed this theory. A proposition is true if it coheres with a group of propositions already considered true. All new knowledge is based on the knowledge systems we had until then, both in science and everyday life. Accordingly, nothing is true in isolation; each of our pieces of knowledge is linked to the system of knowledge.
- Truth as a Pragmatic Opportunity: A theory is true if its explanations are useful in solving life’s problems. William James is a main representative. James understood suitability in a special sense, a sense of value for a particular purpose or context. Suitability, therefore, is adaptation. The meaning of truth is dynamic, where usefulness means:
- Effective solutions to problems.
- Beneficial effects.
- Truth as Consensus: Defended by Peirce, Habermas, and Apel. According to this theory, dialogue is necessary to determine the truth of a proposition. When we consider something true, we believe we have sufficient reasons to convince others. A true proposition is one where those willing to engage in dialogue with others can reach a consensus. However, the question arises whether all partners can agree. If consensus is not a criterion of truth, it might be because the partners lack relevant information. Therefore, all scientific truth is always revisable.
