The universality of logic principles

The universality of logic principles

1. The principles are judgments with which it is possible to build the system of relationships in each science. Logical principles are also considered statements of universal validity that make thought itself possible.

   • Logic is a great field that seeks to study thought to establish valid reasons
   • Thought is considered a process that allows man to obtain a perception of reality.
   • There are four logical principles: Principle of identity, of contradiction, of excluded third party and of sufficient reason.
     • The identity principle is an essential instrument to understand and elaborate the structural and social transformations that occur over time and that characterize the various situations that are generated, as well as for their adequate teaching.
       • Example: The circle is a circle and not a square.
     • The contradiction principle plays an important role in thinking and knowledge. The reasoning in which formal contradictions are found is inconsistent. The principle of contradiction constitutes a reflection of the qualitatively determined character of objects in thought.
       • Example: It is not blue and red, it is red and blue.
     • The principle of the excluded third maintains that everything has to be or not be, but it is not possible, according to the bivalent vision, "to be and not to be" at the same time.
       • Example: That person is innocent or not innocent.
     • The principle of sufficient reason is characterized by one of the essential characteristics of logical thinking: demonstrability This principle responds to a natural demand of our reason: nothing can be nothing more "because yes", because everything obeys a reason.
       • Example: objects fall to the ground for a reason, the law of gravity
