An eccentric philosophy professor was famous

An eccentric philosophy professor was famous for giving his students unusual challenges.

Throughout the semester, his class had explored a wide range of complicated ideas, debated difficult questions, and discussed how people determine what is real and what is merely an assumption.

When the day of the final exam arrived, the students entered the classroom expecting a difficult test.

Everyone took a seat, prepared their pens, and waited for the professor to hand out the questions.

Instead, the professor picked up his own chair, placed it firmly on top of his desk, turned toward the blackboard, and wrote a single question:

“Using everything we have learned this semester, prove that this chair does not exist.”

The students stared at the question in disbelief. Then the room erupted into activity. Pens moved rapidly across paper, erasers rubbed away mistakes, and notebooks filled with complicated arguments.

Some students wrote more than thirty pages in an hour, desperately trying to construct a convincing philosophical explanation for why the chair was not real.

However, one student remained calm. He looked at the question, thought for a moment, wrote down his answer, and handed in his exam in less than a minute.

The professor accepted the paper without comment, leaving everyone else wondering how anyone could possibly answer such a difficult question so quickly.

Several weeks later, the final grades were posted. To the students’ astonishment, the quick-thinking classmate had received an A, even though he had barely written anything.

Curious, they asked him how he had managed to solve the professor’s impossible question with so little effort.

He simply smiled and revealed his entire answer:

“What chair?”
