And the most exact of the sciences are those which deal most with first principles; for those which involve fewer principles are more exact than those which involve additional principles, e.g. arithmetic than geometry.
Bestalde, zientzietan zehatzenak, printzipio lehenei dagozkienak dira batez ere, printzipio gutxiagotik abiatzen direnak gehitzaileak deiturikoak baino zehatzagoak baitira, hala nola aritmetika geometria baino.
