Growing Up

In 384 B.C. when Aristotle was born, he was born in the city-state Stagira.

His father was very famous and was a popular aristocrat.

His dad’s name was Noccomachus and was the doctor to the king of Macedonia, King Amyntas.

Since Aristotle’s dad was a doctor, he became very interested in anatomy and he loved nature.

When he learned, he was probably taught by tutors and he took classes such as science, math, anatomy, and arts.  He was very smart and learned to write and speak Greek.


When Aristotle turned 17, he was still very interested in anatomy and in the arts.

He believed that he was smart, and he knew that he wanted to learn more.

He decided at 17 years old that he would go and join Plato’s Academy which was in Athens.

While Aristotle was at Plato’s Academy, he studied hard and then later, became a teacher there.

He worked and studied at Plato’s Academy for a total of 20 years.

Plato’s Academy

Plato’s Academy was a place to learn, but it was not like the colleges that people attend today.

The classes were not real classes at all, and no specific teacher would teach the students.

The way that this academy worked, the teachers and the students would sit together in groups they would ask questions and then they would debate the answers.

Sometimes, one person would ask a question and another person would try to answer the question and then it would be someone else’s turn.

The point of this kind of teaching was to allow students the ability to ask questions and know that there was more than one answer that was possible.

This taught people to be able to speak out loud what they were thinking instead of just writing it down or staying quiet.


Aristotle decided that he would leave Plato’s Academy in 347 B.C. and he decided to travel around the area.

He went to Turkey and all throughout Greece.


While Aristotle was traveling, he got married and wrote many different books and other works.  Some of them included:

  • “The Parts of Animals.”
  • “The Natural History of Animals.”
  • “The Reproduction of Animals.”

Observations of the World

While Aristotle went on his travels, he had different ideas on how the world should work.

He always was taking notes and wrote down things that he saw.

Not only did Aristotle believe in watching and learning, but he also would take things further and would dissect animals in order to see how their anatomy worked.

Other philosophers thought that this was crazy because they would only do bookwork and think about the world.

They did not believe that people should do hands-on work.

Biology and Science

Aristotle is given credit for doing this because he helped to bring science to life for people even today.

Aristotle also loved biology and he was one of the first people to try to classify animals into different groups.

Aristotle would draw animals and figure out what organs and traits made them function.

He made many discoveries in his time.

Alexander the Great

Alexander the Great

One interesting thing about Aristotle is that he became the tutor of Alexander the Great.

Since his dad knew the king, Philip II of Macedonia asked him if he could teach his son different subjects such as logic, philosophy, math, and more.

Alexander the Great became one of the most known people in Ancient Greek times and he was known as one of the biggest conquerors of the time.

Some people say that this was because of Aristotle’s great teachings.

School of Aristotle

After Aristotle tutored Alexander the Great, he decided that he would open his own school.

He called his school “Peripatetic School,” and it was built in Athens.

He taught different subjects such as politics, philosophy, physics, public speaking, logic, science, and more.

Aristotle’s Teachings

Aristotle has many teachings that we use today such as syllogism.  Syllogism is a type of reasoning that people use today.

Another thing that Aristotle is credited for teaching us is about the five elements of the earth:  air, water, fire, earth, and aether.

Aristotle also taught about four causes, astronomy and “mean,” which is doing things in moderation and not being extreme.
