    "title": "Against the Professors, Books I-VI of Against the Learned",
    "author": "Sextus Empiricus",
    "date": "c. 180-220 CE",
    "summary": "The first six books of Against the Learned examine grammar, rhetoric, geometry, arithmetic, astrology, and music. Sextus targets these disciplines’ theoretical claims while sometimes distinguishing useful practices from disputed dogmatic foundations.",
    "learning": "Identify the target within each discipline, distinguish empirical use from dogmatic foundation, and compare recurring structures of sceptical refutation.",
    "long_summary": "Each book asks what a discipline teaches, how its principles are established, and whether its experts agree. Circular definitions, indeterminate units, proofs depending on what they must demonstrate, and conflicts of method feed criticism.\n\nThe grouping follows a transmitted series, not six independent modern monographs. Sextus does not necessarily abolish everyday reading, calculation, or musical practice; he attacks the status of certain science claimed by theorists. This distinction prevents confusing scepticism with wholesale rejection of skill.",

        "science": "Astronomy, geometry, natural history, and engineering compile Greek, Egyptian, and Roman knowledge. Measurement exists without a modern laboratory.",
        "medicine": "Physicians, midwives, baths, plants, and rudimentary surgery can help; reliable anaesthesia, antisepsis, and antibiotics do not exist.",
        "transport": "On foot, horseback, cart, or ship, road and sea networks connect the Empire. Travel remains slow, costly, and risky.",
        "agriculture": "Grain, vines, olives, pulses, and livestock supply cities and armies; estates, slavery, and tenancy organize part of the labour.",
        "communication": "Imperial couriers, letters on papyrus or tablets, inscriptions, and oral proclamations spread information. Everything is copied by hand.",

For a stone placed beside a stone, iron beside iron, and diamond beside diamond do not unite along a line. Thus the two lines could not become one line. Besides, if there is union when the two lines become one, and a coalescence of the bodies, their separation ought not to occur along the same boundaries, but through different parts being torn apart, so that destruction would also occur. Yet this is not observed to happen. Rather, the boundaries of the bodies, both before juxtaposition and after separation, are such as they appeared to be [before] while in juxtaposition. Therefore the two lines do not become one.",

Une pierre placée contre une pierre, du fer contre du fer et du diamant contre du diamant ne s’unissent pas suivant une ligne. Les deux lignes ne sauraient donc devenir une seule ligne. D’ailleurs, si le fait que les deux lignes deviennent une constituait une union et une coalescence des corps, leur séparation devrait s’accomplir non suivant leurs mêmes limites, mais par l’arrachement de parties différentes, de sorte qu’il y aurait aussi destruction. Or ce n’est pas ce que l’on observe. Les limites des corps, avant leur juxtaposition et après leur séparation, sont telles qu’elles paraissaient être [auparavant] durant la juxtaposition.
