To count an activity as ＂thinking about the physical world＂ is to hold it assessable in the light of the laws of physics; whereas to count an activity as ＂thinking at all＂ is to hold it assessable in the light of the laws of logic. Thus, the kind of generality that distinguishes logic from the special sciences is a generality in the applicability of the norms it provides. Logical laws are more general than laws of the special sciences because they prescribe universally the way in which one ought to think, if one is to think all. Logicism is usually understood to be the thesis that all, or at least large parts of, mathematics can be reduced to logic. This thesis has two sides： （1） all mathematical concepts can be defined in terms of basic logical concepts; （2） all mathematical theorems can be deduced from basic logical truths. According to logicism all terms, including all mathematical terms, are to be given a definite meaning within the basic system. This paper aims at a comparative analysis of the contributions of Frege and Russell to the development of modem logic by reviewing in some detail their essential features and derivations. Without making any pretensions to proffering a definitive resolution of any puzzles, the discussion will, however, raise some fundamental questions, and offer a critical evaluation of the putative success or failure of the logicist programmes of Frege and Russell.展开更多

The site of Losino 15 revealed some traces of a settlement of the Pomeranian and the Wielbark cultures. The most interesting features discovered at the study site are the remains of bloomery furnaces. The site of Losino 15 yielded 10 features interpreted as relics of the bloomery shaft furnace with a pit. They were characterized by a high degree of deterioration-due to the agronomic activities and slope processes, only the bottom part of the slag-pit have been preserved. These are the remains of shaft furnaces with a pit called slag-pit fumace, whose relics are slag-pits filled with slag. The site of Losino 15 yielded slag with a total weight of about 100 kg. Two alternative and temporarily equivalent hypotheses can be proposed here. According to the former one, the creators of the bloomery were representatives of the Pomeranian culture, and in the latter version--they represented the Wielbark culture.展开更多
