Experimentation’s artificiality has parallels in the world of theory. Although
we may think of theories and models as straightforward descriptions of the
material world, identifying its states and properties, they are at best idealizations
of or abstractions from the real world that they purport to represent.
This point is at least as old as Plato’s argument that mathematics must
describe a world of forms that are prior to material reality; mathematicians
in Ancient Greece developed styles of diagrams and technical language that
allowed them to learn about necessary and abstract objects while working
with constructed and concrete ones (Netz 1999). But this point has also
been forcefully made more recently. Scientific theories and laws are ceteris
paribus statements: they do not tell us how the natural world behaves in
its natural states, but rather that a set of objects with such and such properties,
and only those properties, would behave like so (Cartwright 1983).
By science’s own standards, its best theories and laws rarely even apply exactly
to the contrived circumstances of the laboratory.

Professor Anderson thought that because historical parallels are so (much) used unprecisely and uncritically it (would) be (better) to avoid them
