  While SETI is often thought of as a part of radio astronomy with optical
SETI, artifact SETI, METI, and other approaches to finding intelligent life
considered to be allied fields, SETI is better understood as an
interdisciplinary field with many subfields, approaches, and components. In
particular, Robert Bradbury has argued for a broad view of SETI between two
extremes: "orthodox SETI," or radio communication SETI, and a "Dysonian
Approach" that searches for the extreme effects of alien life on its
environment. Here, I build on these ideas and attempt to organize the
terminology and efforts of SETI within a single framework for SETI as an
interdisciplinary and multipronged approach.
