Received 27 January 1999; Accepted 6 April 1999

The choices of the standard equations for massive, massless and tachyonic fermions are examined, on the grounds of desirable features related to the symmetry operations. Linear superpositions of different mass states are revisited, and some possible probability interpretations are suggested.
