Why do you ask?

(2) What were Akiva's beginnings? It is said: Up to the age of forty, he had not yet studied a thing. One time, while standing by the mouth of a well in Lydda, he inquired, "Who hollowed out this stone?" and was told, "Akiva, haven't you read that 'water wears away stone' (Job 14:19)? - it was water falling upon it constantly, day after day." At that, Rabbi Akiva asked himself: Is my mind harder than this stone? I will go and study at least one section of Torah. He went directly to a schoolhouse, and he and his son began reading from a child's tablet. Rabbi Akiva took hold of one end of the tablet, and his son of the other end. The teacher wrote down alef and bet for him, and he learned them; alef to tav, and he learned them; the book of Leviticus, and he learned it. He went on studying until he learned the whole Torah. Then he went and sat before Rabbi Eliezer and Rabbi Joshua. "My masters," he said, "reveal the sense of Mishnah to me." When they told him one halakhah, he went off to reason with himself. This alef, he wondered, what was it written for? That bet - what was it written for? This teaching - what was it uttered for? He kept coming back, kept inquiring of Rabbi Eliezer and Rabbi Joshua, until he reduced his teachers to silence.
