Nobel Laureate or not, Feynman had little patience with
philosophy and
science issues, so I wouldn't quote him on issues of what
science is, as
opposed to what scientists do.
Except maybe for this -
"Science is the belief in the ignorance of experts." - Richard P. Feynman
("What Is Science?", The Physics Teacher, September, 1969, pp.313-320,
originally presented as an address at the 14th Annual Convention of the
National Science Teachers Association in 1966).
