He was probably right

The article begins by introducing Marcus Tullius Cicero, a Roman statesman, lawyer, and philosopher, who lived from 106 to 43 BCE.

In 45 BCE, Cicero wrote Academica, a philosophical work explaining Academic Skepticism, a school of thought he adopted.

This period was tumultuous for Cicero: his political ally Julius Caesar declared himself dictator for life, leading to Caesar's assassination in 44 BCE.

Personally, Cicero had recently divorced his wife of 30 years and suffered the loss of his daughter Tullia in 45 BCE.

Despite these crises, Cicero wrote extensively, influencing medieval Christian scholars, Renaissance thinkers, and the Founders of the American Republic.

His Academica addresses the balance between doubt and certainty in belief, a topic explored through his own experiences and philosophical arguments.
