It is either among singles joined in existence, or not.
Said: the tasallasal water: flowed down slopes. As a term: infinite matters’ ordering joined in existence; its fallaciousness proved varied arguments, as the application-argument and ladder-argument and others. Solidest and firmest, as said, its nullity, infinite ordered joined matters exposed to the absolute number; doubling that number on its like by synthetical mental doubling, the doubling’s number necessarily exceeds the origin-number added on; any two numbers one exceeding other; the exceeder’s accretion conceived only after exhausting all individuals added on: no accretion conceived on the beginning, else no beginning remains, contradiction. The intermediaries ordered successive: had the added-on been infinite, accretion demanded from limitlessness’ nonexistence side, fallacious, accretion conceived only after limit; number’s limit demands the counted’s limit. Also doubling among finite numbers’ properties: positing it infinite matters an impossible positing: may demand other impossibilities, namely the infinite’s limit.
