In seinem Aufsatz, betitelt „Reflections on Hansjakob Seiler’s continuum“, schreibt der französische Mathematiker und Philosoph René Thom Folgendes:

„Finally we recognize that H. Seiler’s continuum is the only known way forward in the education of physical mechanisms permitting us to classify real objects linguistically. I believe this brings in the problem of schematism, famous since Kant: how to form a representative image of a concept (the prototypical referent, as we say today). In his Philosophy of Grammar, O. Jespersen uses as an epigraph Jean-Jaques Rousseau’s maxim: ‚It takes a great deal of philosophy to perceive once what we see around us all the time.‘ From this point of view H. Seiler certainly deserves, beside the title of a great linguist that his work on the Cologne UNITYP project obviously merits, the title of great philosopher“
