A Buddhist Etiology

I am tempted to use the term “Buddhist etiology,” primarily to express the Buddhist theory of the origination of internal world consisting of sentient beings (sattvaloka) or saṃsāric inhabitants and the external world consisting of habitat (bhājanaloka). In certain strands of Buddhism, it may also deal with the origination of saṃsāra and nirvāṇa, and in others with the origination of a human being. The word etiology (or aetiology or ætiology) is said to be the “the study of causation, or origination. The word is derived from the Greek αἰτιολογία, aitiología, ‘giving a reason for’ (αἰτία, aitía, ‘cause,’ and -λογία, -logía).  More completely, etiology is the study of the causes, origins, or reasons behind the way that things are, or the way they function, or it can refer to the causes themselves. The word is commonly used in medicine, (where it is a branch of medicine studying causes of disease) and in philosophy, but also in physics, psychology, government, geography, spatial analysis, theology, and biology, in reference to the causes or origins of various phenomena.” In Buddhist context, too, it can best be employed to express samudayasatya (i.e. causal aspect of saṃsāra) as opposed to duḥkhyasatya (i.e. resultant aspect of saṃsāra). One can also employ this term to express mārgasatya as the cause of nirodhasatya.
