Aristotle’s four causes (or my version of them) may be divided into two groups: an upper group and a lower group. I call the upper group hyperaitia (from Greek hyper, over, above + aitia, cause) and the lower group hypoaitia (from Greek hypo, under, beneath + aitia, cause):
| Causes | Δ time | Δ space |
| hyperaitia | final | formal |
| hypoaitia | efficient | material |
Natural science uses only the lower causes; it is hypoaitial. One might say that Aristotle’s science was hyperaitial since that is where he started. His metaphysics was hylemorphic (or hylomorphic) since it posited that everything has form and matter.
A science that uses only efficient and formal causes may be called dynamorphic. Such is the emerging science of dynamic information.
A top-down science or process, etc. may be called hyperhypo. A bottom-up science or process, etc. may be called hypohyper. A form applied to a material is hyperhypo. A material with emerging form is hypohyper.
