Physics / Field: Thesis: everything we need, are ordinary physical objects and an entity with geometric and electromagnetic properties.
Physics / Field: only describes the actual world - not the possibilities.
Physics / mathematical entities / truth / applicability / Field: Physics requires only the logical truth (iii *) PB (if MB, then M (B * & AXM)) (see the text) - ((s) conditional; anyway modal) - not an assertion like AM, claiming the existence of mathematical entities. - Conclusion: instead of conservatism, consequence and strong consistency we need the modal analogues of these concepts - then no mathematical entities - and no metalogical terms.
