USPOREDBA PETRIĆA I BOŠKOVIĆA
Opravdanje naznačene usporedbe nalazimo u samog Petrića odnosno
Boškovića. Kod Petrića u masivnom uspoređivanju Platona i Aristotela, a kod
Boškovića Newtona i Leibnitza. Petrić i Bošković uspoređuju se već na razini
biografija, a onda sve do razine doktrina.
Premda je metafizika svjetla vrlo stara, a u renesansi obnovljena, specifičnost
Petrićeva pristupa principu svjetla jest njegova aristotelovska metoda.
Njome Petrić dolazi do prvog uzroka ne putem analize gibanja nego svjetla,
kako to stoji u njegovu glavnom djelu Nova de universis philosophia. Bošković
pak radikalizira Newtonovu ideju o silama da bi došao do jednog jedinstvenog
zakona silā. Naročito je to razvio u glavnom djelu Theoria philosophiae
naturalis.
Iako neki aspekti Petrićeve misli izazivaju interes kasnije filozofije, pa i
danas, Boškovićeva ‘teorija’ silā biva aktualnom za modernu fiziku i ‘prirodnu
filozofiju’ sve do danas.

THE COMPARISON OF PETRIĆ AND BOŠKOVIĆ
The justification of the proposed comparison is equally found in Petrić and
in Bošković. In Petrić there is a massive comparison of Plato and Aristotle, and
in Bošković of Newton and Leibnitz. Petrić and Bošković are being compared
from the basic biographical level to the level of their doctrines.
Though the metaphysics of light is very old and had been renewed in the
Renaissance, the specificity of Petrić’s approach to the principle of light is
in his Aristotelian method by which he reaches the first cause not by means
of the analysis of movement, as it is quoted in his work Nova de universis
philosophia, but by means of the analysis of light. On the other hand Bošković
radicalizes Newton’s idea of forces in order to reach the one and unique law
of forces. This he has especially expounded in his major work Theoria philosophiae
naturalis.
