Book excerpt: What is truth? This fascinating spectrum of studies into the various rationalities of our human dealings with life - psychological, aesthetic, economic, spiritual - reveals their joints and calls for a new approach to truth. Putting both classical and contemporary conceptions aside, we find the primogenital ground of truth in the networks of correspondences, adequations, relevancies, and rationales at work in life's becoming. Does this plurivocal differentiation mean that the status of truth is relative? On the contrary, submits Anna-Teresa Tymieniecka, given the universal significance of the crucial instrument of the logos of life, "truth is the vortex of life's ontopoietic unfolding".
