We investigate to what extent a spinor is recovered from S, P, V/sub ..mu../, A/sub ..mu../, and T/sub munu/ satisfying the Fierz identities. To do this, we introduce a parameter representation for the 16 tensor quantities, which takes care of all the Fierz identities, and set up a spinor-determining equation. This equation is solved. The solution contains 4 arbitrary complex numbers. These constants can be determined except an overall phase if we demand that the bilinear forms agree with the original 16 tensor quantities.
