The 14-day rule restricts the culturing of human embryos in vitro for the purposes of scientific research for no longer than 14 days. Since researchers recently developed the capability to exceed the 14-day limit, pressure to modify the rule has started to build. Sophia McCully argues that the limit should be extended to 28 days, listing numerous potential benefits of doing so. We contend that McCully has not engaged with the main reasons why the Warnock Committee set such a (...) limit, and these still remain valid. As a result, her case for an extension of the 14-day rule is not persuasive. (shrink)

Interest in imagination dates back to Plato and Aristotle, but full-length works have been devoted to it only relatively recently by Sartre, McKellar, Furlong, Casey, Johnson, Warnock, Brann, and others. Despite their length and variety, however, these current theories take overly narrow views of this complex phenomenon. Their definitions of “imagination” neglect the multiplicity of its meanings and tend to focus narrowly on the power of imaging alone. But imagination in the fullest, most encompassing sense centers instead on creativity, (...) which involves both imaging and reasoning powers. Current accounts of the operations of imagination narrowly construe it in fixed, immutable terms. But it’s instead a dynamic, evolving synergy of its psychological roots and sociobiological roots. This synergy has transformed the roles of images and symbols in imagination. For example, in the shift from mytheopic to scientific imagination, literacy and formal education fostered abstract symbolic thinking, which differs from mytheopic thinking based on richly concrete associations. The result was “more than cool reason”, but experimental studies show that it’s also more than just dreamy imagery. It’s a dynamic synergy of the two that has transformed both. Current evaluations of imagination’s potentials are also narrow. They tend to focus on its role in mental life while ignoring social and political life. Also, they tend to follow romantic and existentialist customs of extolling imagination’s virtues without soberly critiquing its limitations. Again, they ignore the synergy of psychological, sociological and biological forces that shape mental and social evolution, and promote and constrain imagination in complex ways. For example, Sartre surreally asks us to choose our own nature with an imagination emancipated from institutional and instinctual strictures. Yet making intelligible choices depends on these strictures. In conclusion, current theories define imagination narrowly in terms of imaging, they describe its operations in fixed and immutable terms, and they evaluate its potentials without examining the full interplay of forces shaping it. These shortcomings are remedied by a broader perspective that defines imagination more adequately and comprehensively, and that recognizes it’s complex roots, dynamic operations, and evolving potentials. This paper is based on my 1994 work, The Roots of Imagination, which can be downloaded in full here in PhilPapers. (shrink)

After the death of Wittgenstein, the center of philosophical attention in England shifted from Cambridge to Oxford under the leadership of Ryle, Austin, Strawson and Grice. Hart, Hampshire, Toulmin, Hare, Nowell-Smith, Berlin and Warnock followed them. And this philosophy developed during the period of the fifties a great development made Oxford the center of the most important philosophy in the world. Oxford philosophy made the study of language the primary subject of philosophical inquiry. This study created a method known (...) as linguistic analysis, which was applied in addressing the problems of philosophy of mind, morals, meaning, linguistic communication, and so on. بعد وفاة ڤتجنشتين ، تحول مركز الاهتمام الفلسفى في إنجلترا من كيمبردج إلى أكسفورد تحت ريادة رايل، وأوستن، وستراوسون، وجرايس. وسار في ركابهم هيرت، وهامبشير، وتولمان، وهير، ونويل- سميث، وبرلين، ووارنوك. وتطورت هذه الفلسفة خلال فترة الخمسينيات تطورا عظيما جعل من أكسفورد مركز الفلسفة الأكثر أهمية في العالم. وجعلت فلسفة أكسفورد من دراسة اللغة الموضوع الأساسي للبحث الفلسفي. واصطنعت لهذه الدراسة منهجا عرف بالتحليل اللغوي، جرى تطبيقه في معالجة مشكلات فلسفة العقل، والأخلاق، و المعنى والتواصل اللغوي، ونحوذلك.
