Athemaricorum in Scieniis investizandis, ac tradendis Me-
thodum, qua nempe ex Definitionibus. Postulatis, atque A-
xiomatis Conclusiones demonstrantur, optimam esse tuti(simam.
que veritatis indacandae atque docenda viam, omnium, qui supra
vulzus sapere volunt, unanimis est sententia. Et quidem jure merito. Lt-
enim, cum omnis rei ienota certa ac firma coenitionon, nisi ex certo praecoe
nitis, hauriri ac derivariqueat, haec necessario ab imo praestruenda erunt,
tanquam stabile fundamentum, cui postmodum; nesporte subsidat, aut mi-
nimo impetu pessum eat, totum coenitionis humanae adificium superimpona-
tur. Istius autem nota esse, quae passim Mathesios cultoribus nomine De-
finitionum. Postuilatorum, atque Axiomatum venire solent, nemini dubi-
um esse poterit, qui nobilem istam disciplinam a limine tantum salutaverit.
Definitiones enim nihil aliud sunt, quam terminorum at que nominum; qui-
busres tractandae designantur, apertissima explicationes: Postulata autem,
es Axiomata, seu communes animi Notiones adeo clarae atque perspicna (unt
Lmunciationes, ut iis omnes; qui ipsa vocabula solummodo recte intellexe-
rint, assensum necare nequaquam possint.
Verumenimvero, quamvis haec ita se habeant, nullas tamen, si Ma-
thematicas excipias, fere disciplinas eâ Methodo conscripias reperies; sed
alia toto paene calo ab hac diversa. quà nempe per Definitiones, ex Divisio-
nes, inter se continuo concatenatas, at que hinc inde quaestionibus at que expli-
cationibus
