Formal Logic: Types, Language, and Statements
Formal Logic
Formal logic deals with the validity of arguments by focusing on their formal aspect. It determines when an inference is well-built, meaning the conclusion is properly deduced from the premise.
Types of Formal Logic
- Logic of Statements: Studies the formal validity of arguments by considering only the truth value (true or false) of each statement. It treats statements as a whole, without analyzing the subject and predicate internally.
- Predicate Logic: Analyzes the internal structure of utterances,

- The model is a universal mathematical science.
- Reason is the only instrument to know reality.

Empiricism
Empiricism is a philosophical doctrine that posits experience as the primary source of knowledge. Developed around the 17th and 18th centuries, with key figures like Locke and Hume, this theory asserts that sense experience is the sole origin of human knowledge. Empiricists believe we can only access the pure phenomenon itself, and since all knowledge stems from experience, it must be acquired. The mind, devoid of innate ideas, is considered a tabula rasa (blank slate). Consequently, the

Kant: Bridging Empiricism and Rationalism
Kant, the 18th-century philosopher, found himself positioned between two opposing theories. On one hand, empiricism asserts that all knowledge originates from experience and denies the existence of innate ideas. On the other hand, rationalism claims that knowledge can be derived solely from reason and that innate ideas exist. Kant resolved this contradiction by stating that we need both faculties: the senses and reason. Through our senses, objects are given

Science is a systematic and organized body of knowledge derived from the study of human activity, utilizing laws and general principles.
Key features of science include its focus on reality, accuracy, and, where possible, mathematical formulation.
Formal Science
Formal sciences, such as logic and mathematics, do not refer to objects observable by the senses. They provide necessary, universal, and consistent information based on the coherence of reason itself.
