Where was Aristotle born and when?

Aristotle was born in Stagira, to the north of Greece, in 384 BCE.

What significant event happened in Aristotle's life in 367 BCE?

In 367 BCE, Aristotle moved to Athens and became part of Plato's circle, where he received teaching at Plato's Academy.

Who did Aristotle tutor after the death of Plato?

After Plato's death in 347 BCE, Aristotle traveled around the region before being caught by Philip II, King of Macedonia, to tutor his son, who would become Alexander the Great.

What happened to Aristotle in 335 BCE?

In 335 BCE, Aristotle left the side of Alexander the Great to set up his own school, the Lyceum.

How many of Aristotle's works have survived to this day?

Only about 30 of Aristotle's works have survived, which are likely rewrites or edits by a man named Andronicus who found them over 200 years later.

What was the nature of Aristotle's lost works?

Aristotle's lost works were more poetic, publicly aimed, and beautifully styled, possibly guides for fellow tutors, jottings of thought, research notes, or lecture notes.

How did Aristotle's approach to knowledge differ from Plato's?

While Plato was a man of idealism, influenced by the war-born philosophy of his time, Aristotle became a man of empiricism, focusing on the material world and clear, distinct concepts.

What is the significance of Aristotle's system of classification and reduction of understanding?

Aristotle's system of classification and reduction of understanding is key to his approach to knowledge, where he systematized each section of knowledge within a set of guiding rules, similar to how geometry was systematized.

What are the three laws of thought attributed to Aristotle?

The three laws of thought attributed to Aristotle are the law of identity (a equals a), the law of non-contradiction (a does not equal not a), and the law of excluded middle (either a or not a, but not both).

What is the critique of the law of identity in the context of the real world?

The law of identity (a equals a) is criticized for being a tautology with no explanatory value in the real world, as things change over time and are not the same at every point in time.

How does the law of non-contradiction face challenges when applied to subjective truths?

The law of non-contradiction (a does not equal not a) faces challenges with subjective truths, as what is true or false can be based on parameters set by society or individual perception, and thus something can be both true and false depending on the context.

What is the law of excluded middle, and why is it problematic?

The law of excluded middle states that everything must either be or not be (either a or not a), but not both. It is problematic because in the real world, there are often shades of gray and situations where something can be both at different times or under different conditions.

Why are Aristotle's laws of thought not considered absolute by some philosophers?

Aristotle's laws of thought are not considered absolute by some philosophers because they are based on axioms that support classical logic, which is not the only logical structure, and because they do not always hold true in the mutable and time-dependent real world.
