th.t. / Fraassen: it is often not clear whether they refer to concrete or mathematical entities. - E.g. "powers"/power: sometimes regarded as not specifically mathematically, only the existence of certain features is maintained. - This is controversial._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
