We will formulate some analogous higher-order versions of Skolem’s paradox and assess the generalizability of two solutions for Skolem’s paradox to these paradoxes: the textbook approach and that of Bays (2000). We argue that the textbook approach to handle Skolem’s paradox cannot be generalized to solve the parallel higher-order paradoxes, unless it is augmented by the claim that there is no unique language within which the practice of mathematics can be formalized. Then, we argue that Bays’ solution to the original (...) Skolem’s paradox, unlike the textbook solution, can be generalized to solve the higher-order paradoxes without any implication about the possibility or order of a language in which mathematical practice is to be formalized.

Some analogous higher-order versions of Skolem’s paradox will be introduced. The generalizability of two solutions for Skolem’s paradox will be assessed: the course-book approach and Bays’ one. Bays’ solution to Skolem’s paradox, unlike the course-book solution, can be generalized to solve the higher-order paradoxes without any implication about the possibility or order of a language in which mathematical practice is to be formalized.

The controversy about research on human embryonic stem cells raises many fundamental ethical and religious questions, especially about the sanctity of lifeand the Divine mandate of human dominion over nature. This paper reviews the different perspectives of three monotheistic religions on the use of embryo for stem cell research. Looking at the religious perspectives, it shows us that Islam and Judaism support most forms of stem cell research. Both of them express their beliefs on when life begins or what the (...) role of scientists in stem cell research is by interpreting specific religious texts. Although Christianity has put the issue of stem cell research on the forefront of its agenda, they do not point to any specific biblical text that supports their concept of when life begins. While science cannot answer the question of when life begins, Christianity, Judaism and Islam have answered the question in some ways. (shrink)
