Mondrian's idea of rhythm is based on "anti-sequential repetition'. If visual rhythm is only plausible by way of producing repetitive or sequential motifs, then we need to establish whether or not it is possible to identify Mondrian's specific idea of rhythm, not only in terms of how Mondrian himself put it, but in terms which accord with existing theories of rhythm within modern Western thought. So how does Mondrian's rhythm compare to the ideas of other theorists: does the word "rhythm", as Mondrian uses it, imply significations and associations completely at odds with those of other thinkers, especially those from within the Western tradition? Is there any common understanding of rhythm between Western and Eastern, between ancient and modern thought, e.g., from Europe, India, Java, Africa, China, and Japan, from early Greek thought to that of our time? As Wittgenstein suggests, whether a particular word is necessary "in the ostensive definition" is very much a matter of whether without that word "the other person takes the definition otherwise than I wish" (Wittgenstein 1958, 14e).
