Hi. Now I can translate that problematic passage for me in John Philoponus’ book.
aporousi de tines (Some people find themselves at a loss.),
ei panta ta onta e^ ansthe^ta estin e^ noe^ta (If every thing is either perceived by sense or perceived by intelligence),
to de aisthe^ton kai noe^ton to^n pros ti (and if things perceived by sense or by intelligence are such things as exist only relatively),
oukoun kai panta ta onta estai to^n pros ti, kai to theion, (then won’t it be so that everything exist only relatively, even God, too ?),
hoper estin atopon (To think that is paradoxical).
