Proceeding from the principles of Euclidean geometry and absolute time a generalization of the classical theory of gravitation for high velocities is given. The new theory is applied to the redshift of spectral lines, the deviation of light passing the sun, and the secular motion of the perihelion of Mercury. A comparison with the results obtained from the theory of general relativity, though not beyond any doubt, seems to be favourable for the new theory, and to support the view, formerly (...) held by Driesch, Dingler, May, and other philosophers of science, that the foundations of classical physics need not be given up.

It is shown that quantum mechanics cannot be formulated as a stochastic theory involving a probability distribution function of position and momentum. This is done by showing that the most general distribution function which yields the proper quantum mechanical marginal distributions cannot consistently be used to predict the expectations of observables if phase space integration is used. Implications relating to the possibility of establishing a "hidden" variable theory of quantum mechanics are discussed.
