One ought to be "Marxist' with the same naturalness with which one is "Newtonian" in physics, or "Pasteurian" in biology, considering that if facts determine new concepts, these new concepts will never divest themselves of that portion of truth possessed by the older concepts they have outdated.

Philosophy treats of physics where a more careful knowledge is required because the problems which come under this head are numerous... So the reader of Ctesibius or Archimedes and the other writers of treatises of the same class will not be able to appreciate them unless he has been trained in these subjects by the philosophers.
Vitruvius
Science has taught... me to be careful how I adopt a view which jumps with my preconceptions, and to require stronger evidence for such belief than for one to which I was previously hostile. My business is to teach my aspirations to conform themselves to fact, not to try and make facts harmonise with my aspirations.
Thomas Henry Huxley
