أركسيلاوس
لكل حجة حجة مضادة تعادلها قوةً، فعلينا أن نعلّق الحكم في كل شيء – ومع ذلك نستطيع أن نتصرف بحسب ما يبدو معقولًا.
التموضع
رئيس الأكاديمية منذ نحو 268 ق.م الذي حوّل مدرسة أفلاطون إلى الشك: جادل كسقراط ضد كل موقف، وبخاصة ضد دعوى الرواقيين بأن بعض الانطباعات لا يمكن أن تكون كاذبة، وأوصى بتعليق الحكم في كل شيء.
الأفكار الرئيسة
- تعليق الحكم (إيبوخي) في كل شيء
- نقد الانطباع المعرفي الرواقي
- الحجاج السقراطي ضد كل رأي
- المعقول (eulogon) هاديًا للفعل

Arcesilaus appealed to Socrates’ avowal of knowing nothing and radicalised it: not even this can be known, so he withheld assent on everything (Cicero, Academica I.45). Cicero, Academica I.44–45; SEP “Arcesilaus”

الموقف
Arcesilaus began what later writers called the Middle or New Academy. He presented his scepticism as a return to Socrates, who claimed to know only that he knew nothing, and to the questioning Plato of the dialogues: instead of stating his own view he argued against whatever his listeners proposed, so that, as Cicero puts it, equal weight of reasons on both sides would lead them to withhold assent. His main target was the Stoic theory of knowledge of Zeno of Citium. Zeno held that there are “cognitive impressions” (phantasiai katalēptikai) which come from what is and are stamped in such a way that they could not come from what is not, and that the wise person assents only to these. Arcesilaus replied that for every true impression there could be a false one indistinguishable from it – twins, eggs, dreams, madness. If so, no impression is cognitive, and the wise person, who never holds mere opinions, must suspend judgement (epochē) on everything. To the objection that this makes action impossible he answered, according to Sextus, that one can act on what is “reasonable” (eulogon). Whether he held these views himself or only drew out consequences of Stoic premises is debated. The Stoic Ariston mocked him as “Plato in front, Pyrrho behind, Diodorus in the middle”, and how much he owed to Pyrrho is still an open question. Carneades carried his method further; Cicero wrote within this Academic tradition, and Augustine argued against it.
الحياة والسياق
Arcesilaus was born around 316/315 BCE in Pitane in Aeolis, on the coast of Asia Minor. After studying mathematics he came to Athens, where he first heard Theophrastus, Aristotle’s successor in the Lyceum, and then joined Plato’s Academy under Polemo and Crantor. Around 268–264 BCE, on the death of Crates of Athens (not the Cynic Crates of Thebes), he became head of the Academy. Diogenes Laertius (IV 28–45) describes a witty, generous teacher with a large following. He wrote nothing; his arguments are known from Cicero, Sextus Empiricus, Plutarch and Diogenes Laertius. He died around 241/240 BCE at the age of 75.
