No student or colleague of Marjorie Grene will miss her incisive
presence in these papers on the study and nature of living nature, and
we believe the new reader will quickly join the stimulating discussion
and critique which Professor Grene steadily provokes. For years she has
worked with equally sure knowledge in the classical domain of philosophy
and in modern epistemological inquiry, equally philosopher of science
and metaphysician. Moreover, she has the deeply sensible notion that she
should be a critically intelligent learner as much as an imaginatively
original thinker, and as a result she has brought insightful expository
readings of other philosophers and scientists to her own work. We were
most fortunate that Marjorie Grene was willing to spend a full semester
of a recent leave here in Boston, and we have on other occasions sought
her participation in our colloquia and elsewhere. Now we have the
pleasure of including among the Boston Studies in the Philosophy of
Science this generous selection from Grene's philosophical inquiries
into the understanding of the natural world, and of the men and women in
it. Boston University Center for the R. S. COHEN Philosophy and History

spottily - years from 1946 ('On Some Distinctions between Men and
Brutes') to 1974 ('On the Nature of Natural Necessity').
