From the 1983 introduction, a caveat lector :
| "At the present time there is no direct experimental evidence that supersymmetry is a fundamental symmetry of nature, but the current level of activity in the field indicates that many physicists share our belief that such evidence will eventually emerge. On the theoretical side, the symmetry makes it possible to build models with (super)natural hierarchies. On esthetic grounds, the idea of a superunified theory is very appealing. Even if supersymmetry and supergravity are not the ultimate theory, their study has increased our understanding of classical and quantum field theory, and they may be an important step in the understanding of some yet unknown, correct theory of nature." |
