Types of concepts: logic for all
We are constantly confronted with the logical laws in everyday life. But, unfortunately, only a few faculties in higher educational institutions fully study this science.
Subsequently, Aristotle's ideas were modifiedthinker of the Renaissance Francis Bacon, one of the first empiricists of his time. The philosopher gave his treatise the name "New Organon". He considered Aristotle's reflections with a grain of skepticism, believing that the task of science was to design a new method of cognition and benefit all people. Bacon criticized the old logic, which, in his opinion, brought only confusion in the general system of knowledge about thinking. He put above all experience and an inductive method.
It is worth noting that especially intensivelythe logic developed in the 20th century, turning into a probabilistic, mathematical, clear and harmonious system. But up to now formal logical laws have great methodological significance for all sciences.
Its laws include types of concepts.Logic constructs a scheme of presentation, which is a chain of "concept - proposition (or statement) - inference". The simplest, but at the same time, fundamental is the concept. Before constructing a statement and making a conclusion (conclusion) on its basis, it is necessary to have the concept of an object, to comprehend its essential features. These are not individual images of sensory perception, on which creative thinking is most often built. Speaking of signs, they mean specific features of difference or similarity. A distinctive feature is a property that is inherent only in this particular subject.
The concept is a conceivable reflection in the form of a general aggregate (or unity) of the essential and common attributes of a particular object.
Logic views types of concepts, exampleswhich are very easy to find. Saying the word "cat", we imagine a specific set of features: claws, wool, mustaches, meow, catching mice. This set itself is a separate concept, so we can say that the concept of "cat" is complex. It includes other concepts, which have already been mentioned above.
Types of concepts
Concepts can be:
1.Registrants (answer the questions "what kind of individual?", "When?", "Where?"). Examples of such concepts: "people who live today in Ivanovo", "the island of Madagascar", "Fedor Dostoevsky." They, in turn, are divided into single (those that mean one specific subject - "Jack London") and general ("writer", "state").
2.Unregistered ("word", "animals", "man"). They can only be defined qualitatively, have an infinite volume of concepts included in them, as a result of which many of their elements can not be accounted for. These types of concepts sometimes divide logic into open (non-registered) and closed (registering).
3. Non-empty and empty on the basis of conformity or inconsistency of a concrete concept to anything in the real world.
4. Abstract and concrete. The first are concepts about the relationship or properties of the object ("honor", "dignity", "courage"), while the latter speak of specific objects ("pillar", "hive").
5. Negative (speaking of the lack of properties of a certain object, for example, "not a person", "not a cat") and positive ("cat", "man").
6. Relative and irrelevant.These types of concept of logic characterize as dependent and independent of each other. That is, for example, the concepts of "grapes" and "leg" do not depend on each other in any way, therefore they can be considered as irrelevant.
Formal logic has a number of shortcomings thatseveral centuries have been revealed by the most experienced thinkers. Therefore, modern logic, while respecting the principles of formal, but still different from the latter by its more perfect structure. This science also widely uses mathematics for various calculations. But the types of definitions of concepts in logic do not lose their relevance to today. Therefore, every thinking person simply needs to become familiar with the structure of such a term as the "concept".
