阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
When it comes to Albert Einstein (1879-1955), it's easy to imagine an old, crazy-haired genius. But before he ever came up with the theory of relativity, Einstein was a 23-year-old patent clerk, working for the minimum wage. Young Einstein decided to earn some extra cash tutoring physics. He put up an ad, and Maurice Solovine, a student of philosophy, responded. The two did not do much traditional studying, but instead chatted about philosophy. Conrad Habicht , a mathematician and a friend of Einstein, joined their debates. They jokingly called themselves the Olympia Academy.
We’ve gathered together some books the members of the Olympia Academy read and discussed. Maybe the literature that inspired Einstein can inspire you to be clever, too.
A Treatise of Human Nature by David Hume
David Hume, a 18th-century Scottish philosopher, was always suspicious. He believed “everything we know is really just a matter of probability”. He argued “reason doesn’t motivate people’’， which led to all sorts of questions， such as “So what’s motivating you to write this?”
“The chief benefit ，which results from philosophy, arises in an indirect manner, and more from its secret insensible influence, than from its immediate application,” Hume wrote.
Analysis of Sensations by Ernst Mach
An Austrian philosopher Ernst Mach wrote about how mysterious senses are. In an attempt to figure out how humans experience balance, Mach cleverly built a turning chairs , which used shades of gray bands to show that the colors people saw were deeply affected by the colors around them.
Science and Hypothesis by Henri Poincare
Henri Poincare,a 19th-century French philosopher, was also a theoretical physicist ，an engineer and a mathematician. At college, he was fantastic at math. He created1 his special theory and wrote Science and Hypothesis, Some of his thoughts actually sowed the seeds for Einstein’s theory of relativity,such as the idea that time is relative.
