The literature relating to extraterrestrial intelligence (ETI) is surveyed to provide a basis for judging the extraterrestrial hypothesis to be an acceptable alternative concept for use in analyzing UFO phenomena. Other common issues facing ufology, ranging from the general argument about its scientificness to concerns about specific and puzzling characteristics of some reports are addressed.
