Abstract
This is the second volume of an "essay in existential philosophy." The first, published in 1977, was intended to "do justice to certain experiential givens of immediate experience" which, once subjected to "severe" testing, could be established as "scientific hypotheses at the level of an existential critique of knowledge". The second volume now means to provide "an ensemble of ideal base intuitions, expressible as a 'system', of which each constitutes the concrete taking of a position before a certain state of things in the existential domain". Its method is to work from descriptions of "the existent in the domain of action" in order to find "kernels of convergence, centers of autonomy, that is structures," and so to be able to ask, finally, about the ground of these in a transcendent act of being.
