From the pen of Professor Geach we have learnt to expect the fastidious art of the microscopist. Not microscopy for its own sake, however, but microscopy as the vigilant servant, ensuring that large views, if and when they are built, shall be built only from sound materials. The present volume is a collection of nine papers—some previously published in journals, and some appearing for the first time. They exhibit the author’s painstaking skill in logical analysis, and his predilection for the (...) paths trodden by Aquinas and the later Wittgenstein. If they invite the charge of lengthy and sometimes tedious hair-splitting, the author has his answer ready: often hair-splitting is the only way to attain the truth. (shrink)
