[3] Demonstration, or clearly showing (a gamut that ranges from mere pointing to more sophisticated strategies such as chemical reactions), can possibly be used in portraying ideas such as defining words.
At first, simple observation and communication through pointing to an object, area, or place, like the sun, moon, or a large mountain top, occurs.
Further, basic concepts centered on time, space, and mathematics are first required to demonstrate and teach probable theories that accurately describe universal phenomenon such as nature, planets, species, and the world around us.
The history of phenomenon demonstrating concepts, which lead to specific definitions, goes back to the careful observations of ancient Greek philosophers and natural philosophy.
John Longeway notes that in the Middle Ages, the theory of demonstration, which developed the thinking in Aristotle's Posterior Analytics, was considered "the culmination of logic".
