Is man a biological being with certain functions?

What Aristotle said?

Aristotle is considered to be one of the greatest Greek philosopher in the history of mankind. He was born in 384_BCE and died in 322_BCE .He was the student of Plato.

One of the great contribution he made is about the functions of human beings. According to him, man is a biological being who has certain functions. These functions are:

·         Eating

·         Perceiving,

·         Having children or reproduce,

·         Thinking, and

·         Doing things.

Aristotle called these functions as the characteristics of living organisms. Talking about the function of eating, a man eats to fulfill his need for food and bodily nourishment so he can grow and survive. The function of perception is to perceive the external stimulus and give responses accordingly. Man also has the characteristic of reproduction, which helps him to reproduce and extend its species. Thinking is the highest level of function which exists in higher forms of living beings only i.e. humans. Humans have the ability to use their mind to think, examine and analyze things and events around them. This ability helps them in understanding of the world. Through this function, human beings gain knowledge. Doing things is another function of human beings according to Aristotle. It means that a human perform certain things and activities throughout their life which could be anything e.g. looking at a picture, cooking a meal or reading a book.
