many other hypotheses to be proposed in the past half century
The recognized weaknesses of Laplace"s hypothesis have caused
many other hypotheses to be proposed in the past half century.
The hypotheses of Faye, Lockyer, du Ligondes, See, Arrhenius,
and Chamberlin and Moulton include many of the features of
Kant"s or Laplace"s hypotheses, but all of them advance and
develop other ideas. It is unfortunate that space limits do not
permit us to discuss the new features of each hypothesis.
