Projections (Star Trek: Voyager) Projections (Star Trek: Voyager) "Projections" is the 19th (3rd in the ) episode of the American science fiction television program "". Originally slated for the first season, the episode originally aired on September 11, 1995, and tells the story of having an identity crisis on the holodeck regarding whether he or the world around him is the illusion. Brannon Braga compared "Projections" to the work of René Descartes, and wrote the episode around the premise of "cogito ergo sum", questioning whether the Doctor or the "Voyager" is the illusion. Beating out LeVar Burton (Geordi La Forge) for the guest appearance,
Cogito, ergo sum itself is good and pleasant (...) and if one who sees is conscious that he sees, one who hears that he hears, one who walks that he walks and similarly for all the other human activities there is a faculty that is conscious of their exercise, so that whenever we perceive, we are conscious that we perceive, and whenever we think, we are conscious that we think, and to be conscious that we are perceiving or thinking is to be conscious that we exist... ("Nicomachean Ethics", 1170a25 ff.) Augustine of Hippo in "De Civitate Dei" writes "Si […] fallor, sum"
