Following his retirement from teaching in 1972 J. M. Bocheński entered into a creative phase of his scholarly career characterized by, among other things, a marked shift to "naturalism' to the detriment of philosophical "speculation' of any kind (comprising much of classical metaphysics, "world views', "ideologies, "moralizing'—for him so many nefarious "superstitions'). During this period he examined issues which bear on the human condition in a way that was at once constructive and critical—constructive by virtue of the logical analyses of such concepts as authority, critical by dint of his refusal to take seriously any so-called "anthropocentric'/"humanist' thinking attempting to secure a special standing for "Man' in the world. These attitudes come to expression in his last work devoted to worldly wisdom, the practical rationality required to ensure a long and happy life. I examine, first, some of the background of this work, with an eye to the naturalism it is based on, provide a schematic overview of the contents of the study, and concentrate on a couple of key issues related to the question as Bocheński understood it. The salient issue concerns his insistence that whatever else it may be the wisdom that is conducive to the long and happy life is not to be confused, conceptually, with any sort of morality: worldly wisdom and the categorical commands of morality stand in no essential relation to each other and may indeed be contradictory … to the detriment of morality, according to Bocheński. Throughout, but especially in the concluding section, I express some doubts about the cogency of this position.
