I think we should see the Vedas in an extremely broad light , it teaches values to all classes of men as well as social mobility.
It’s clear that superior is a relative term .
To an extremely uncultivated fellow, values would mean something quite different than to a highly educated and cultured person , whose values and knowledge cultivation are in different places .
Naturally, Betrand Russell, in setting up his school in Sussex,  meant that he wants to teach something superior, than the students currently understand.
But Betrand himself , may not ,  because of perhaps excessive attachment to his obviously highly cultured intelligence, be able to penetrate an intellectual platform and further  understand a super subjective plane,  taught by  self realised souls and the best of the theologians.
That super subjective realm points to beauty and artistry and existence that is  far superior to the ever changing and fleeting existence in conditioned material life . Nevertheless, such knowledge can be understood by developing a deeply humble and respectful spirit and recognition of superiors.

Further ..Vedas means knowledge, so the relative knowledge Bertrand adopted and shared , parts  of which would parallel the vedas , is essential work, my only point was , Bertrand limited himself.  By attachment to an intellect , and  what he shared was also  limited to his  own ,and others subjective opinions ,  for instance to assume the orderly universe is not orderly, or that the consciousness from where such order came , had no intention of communicating its purposes to other consciousness particles would seem not to be logical . Science is  understood primarily through witnessing objectively, so excellent education will open students up to rational logical thinking and objective science.
