He is author of widely used primers in critical thinking and ethical practice and of a variety of unconventional philosophical books and essays.

Weston's philosophical project as a whole advances an expansive "toolbox" for critical, creative, and constructive thinking, especially for purposes of social and environmental re-imagination and pragmatic ethical practice.

[9] This view may be identified with deconstruction, but too often, Weston argues, This reconstructive project calls on a set of skills and concepts less often recognized and valued in philosophy.

[12] At the same time, he also argues for a "multicentric" approach to reconstituting the human relation to the more-than-human world, as opposed to the "mono-centrism" that could either be human-centered (anthropocentric) or larger-than-human but still "centered" in the sense that one dimension and model for values determines who or what morally counts and why.

Finally, just as ethical practice becomes intelligent, creative, critical engagement with problematic situations and possibilities rather than "puzzle-solving", so even the widely taught and conventional field of critical thinking becomes something more than a matter of testing someone else's arguments for "fallacies", but rather a constructive and open-ended process of framing one's own arguments and energetically recasting and exploring others' lines of thought.

Some of the more noted and often-reprinted of these are (original appearances only): Critics argue that Weston's notions of "originary ethics" and "reconstructive engagement" offer little or no concrete guidance, especially in less-than-optimal situations in which choices nonetheless must be made.
