This text is more a free opinion than a traditional scientific paper.
It shows some intrinsic contradictions faced by quantum chemistry, sch
ematizes some distinct periods of the discipline. It claims that some
tasks, especially the construction of models for a qualitative intelli
gibility of the molecular world, have been neglected to the benefit of
numerism. It underlines some intellectual challenges, which concern t
he interfaces with both chemistry and solid stare physics, which may i
mprove the image of our discipline. (C) 1998 Elsevier Science B.V.
