In comparing the later Pyrrhonism with the teachings of Pyrrho, we would sharply contrast the moral attitude of the two. With Pyrrho equilibrium of soul was a means to be applied to his positive theory of life; with the later Pyrrhoneans it was the end to be attained. We would attribute, however, the empirical tendency shown during the whole history of Pyrrhonism to Pyrrho as its originator. He was an empirical philosopher, and the result of his influence in this respect, as seen in the subsequent development of the school, stands in marked contrast to the dialectic spirit of the Academic Scepsis. The empiricism of the school is shown in its scientific lore, in the fact that so many of the Sceptics were physicians, and in the character of the ten Tropes of ἐποχή. We may safely affirm that the foundation principles of Pyrrhonism are due to Pyrrho, and the originality which gave the school its power. The elaborated arguments, however, and the details of its formulae belong to later times.
Coming now to the relation of Pyrrhonism to the Academy, the connection between the two is difficult to exactly determine, between the time of Pyrrho and that of Aenesidemus. Scepticism in the Academy was, however, never absolutely identical with Pyrrhonism, although at certain periods of the history of the Academy the difference was slight. We can trace throughout the evolution of doubt, as shown to us in Pyrrhonism, and in Academic Scepticism, the different results which followed the difference in origin of the two movements, and these differences followed according to general laws of development of thought. Arcesilaus, who introduced doubt into the Academy, claimed to return to the dialectic of Socrates, and suppressing the lectures,[1] which were the method of teaching in the later schools of philosophy, introduced discussions instead, as being more decidedly a Socratic method. Although, according to Sextus, he was the one leader of the Academy whose Scepticism most nearly approached that of Pyrrhonism,[2] yet underneath his whole teaching lay that dialectic principle so thoroughly in opposition to the empiricism of Pyrrho. The belief of Socrates and Plato in the existence of absolute truth never entirely lost its influence over the Academy, but was like a hidden germ, destined to reappear after Scepticism had passed away. It finally led the Academy back to Dogmatism, and prepared the way for the Eclecticism with which it disappeared from history.

The history of Pyrrhonism and that of Academic Scepticism were for a time contemporaneous. The immediate follower of Pyrrho, Timon, called by Sextus the "prophet of Pyrrho,"[1] was a contemporary of Arcesilaus. That he did not consider the Scepticism of the Academy identical with Pyrrhonism is proved from the fact that he did not himself join the Academy, but was, on the contrary, far from doing so. That he regarded Arcesilaus as a Dogmatic is evident from his writings.[2] One day, on seeing the chief of the Academy approaching, he cried out, "What are you doing here among us who are free?"[3] After the death of Timon, the Pyrrhonean School had no representative till the time of Ptolemy of Cyrene,[4] and Greek Scepticism was represented by the Academy. That Pyrrho had a strong influence over Arcesilaus, the founder of the Middle Academy, is evident[5]; but there was also never a time when the Academy entirely broke away from all the teachings of Plato, even in their deepest doubt.[6] It is true that Arcesilaus removed, nominally as well as in spirit, some of the dialogues of Plato from the Academy, but only those that bore a dogmatic character, while those that presented a more decided Socratic mode of questioning without reaching any decided result, men regarded as authority for Scepticism.
