In any relativistictheory this difficulty occurs, even in the old classical theory of Lorentz.
在任何相对性理论中(负能态)这个困难都存在着，它甚至早在洛伦兹的旧经典理论中就已经存在。

The early workers in relativistictheory were very much impressed by the symmetry between space and time and wanted to cling to it— to hold onto it at all costs.
