 He has explored different forms of writing and varied terminologies for expressing what resists expression, based on the conviction that such a resistance requires constant vigilance and innovative writing, the constant production and transformation of forms of knowledge, especially including philosophy, whose relations to art, literature, science, and religion enrich it profoundly with novel and imaginative questions and answers.He began in American pragmatism, reading it to question itself fundamentally and to entail the "inexhaustibility" of nature and reason, the mysteriousness of things.He wrote several books on ordinality and an "ordinal metaphysics", influenced by his mentor, Justus Buchler.
