Pulses (laser)Let's be clear about patterns-for. For doesn't mean for a conscious (human) observer. It means that in order for there to be a pattern there has to be 1+n objects.
A rhythm is an interaction between 1+n objects. An element of rhythm is called a beat. Think of sound. Lots and lots of beats happening quickly (frequency) result in tones. A sonic beat requires one frequency to be canceled out. Rhythms positively guarantee that there is always at least one withdrawn object in the vicinity. Something executes the canceling out of 1+n frequencies, producing a pulse or sequence of pulses.
Heard sound, for instance, is when beats interfere with the beats already occurring in your ear.
The configuration space in which the patterns of the patterns of the patterns...happen is what Jarrod Fowler calls rhythmicity, and Quentin Meillassoux calls hyperchaos. Why chaos? From this perspective (OOO), because of that 1+n. At least one object is not accounted for in the system—for there to be a system. There is at least one contradiction at any state of the configuration space. This is what reality is.
