The Third Meeting Concept and Abstraction
Concept Concept is a mental sign whereby we grasp a certain essence ( a mental sign of the essence) Example: summer house, tennis club relation, situation, car
Concept,Word and sentence Concept is the small unit of intellection which becomes the elements of judgment in a sentence.
Distinction between concept and the essence The concept signifies what is understood by the mind insofar as it is in the mind Examples: “Man” or “horse” The essence is the intelligible aspect of reality that is grasped by the mind. It is the manner of being of a thing Example “continent” or “triange”
Concept signifies the essence of things Essence means any intelligible property of things, and not just the nature of a substance Examples: “redness” or “roundness” of the ball so, the concept signifies what a thing is
Clear concept When it signifies an essence accurately Example: We understand clearly what a “door” or “ hand”
Vague concept When we do not have enough knowledge to be able to formulate judgment about it Examples: Hyperboles, aminoacid
Erroneous concept Not because it makes false affirmation but because some intelligible notes are mistakenly attributed to it Examples; A wrong idea of freedom A wrong idea of the nature of man
Concept and Image • Image refers to the sensible aspect of reality, whereas the concept refers to the intelligible aspect. • Examples: Yellow
Concept and Reality • Concept makes us know reality • Examples” “turtle”
Abstraction • Abstrare means taking out from the concrete object. • That is why it is important to illustrate general ideas with concrete examples
