There are many currents in philosophical writings, that deal with today's serious ecological problems and the catastrophes they engender. The aim of this book is to show the diversity of these currents and to judge them on the basis of their ability to provide us with concrete tools for getting out of the ecological impasse in which we find ourselves today, notably the urgency to find new types of ecological and human management. Some of these currents are hopeless: they only offer the prospect of a mental adaptation to these catastrophes, or invite us to leave planet earth and take refuge on other planets. Others, of a cynical bent, openly support the forces that have led to the current situation of 'ecological bankruptcy', arguing that the same economic system that has led us to the current ecological impasse will be able to provide us with miraculous technical solutions for our salvation. Still others, the vast majority, are so cut off from the realities of today's economic world, and in particular from the problems of practical business management, that their very general views offer very few operational solutions for changing the situation. And yet there are some philosophies, admittedly very few in number, that seem appropriate to the radical transformation that is needed of the management of capitalist firms: the philosophy of catastrophes is not necessarily synonymous with a catastrophe of philosophies. The author draws on philosophy , economics, accounting, and history to address what many consider humanity's most serious challenge.
