Though Bernard Lonergan is often counted among the so-called “Transcendental Thomists”, this article offers a re-appraisal of his theory of understanding with a renewed emphasis on its a posteriori, rather than a priori, approach. For Lonergan, because understanding is experienced, it can be investigated empirically. It is the further conviction of the author that the experience in which understanding gives itself is a bodily experience. This is the case both in how the experience emerges from biological processes, but also appears (...) within the “phenomenological body” of human conscious awareness. Lonergan’s cognitional theory is compared with Maurice Blondel’s theory of embodied reason to elucidate the former and with Eugene Gendlin’s notion of a bodily “felt-experience” to elucidate the latter. A few final, exploratory comments are made with regard to the dynamics of symbolization, formulation, and expression by linking Gendlin’s work with Lonergan’s Verbum articles. (shrink)
