The Understanding of Nature: Essays in the Philosophy of Biology . By Marjorie Grene. Boston Studies in the Philosophy of Science, 23. Dordrecht, Reidel, 1974, pp. xii + 374. Cloth, US $32.50; Paper, US $17.50.

Marjorie Grene is well known to those of us interested in the philosophy of biology. Whilst most of us were in high-school, or before, she was hacking her way through the thorny thickets of philosophical nonsense with which so many emminent evolutionary biologists surround their science, and with truly admirable energy she has continued this practice right up to today. It is therefore, in itself, a welcome fact that her many essays on the philosophy of biology are now gathered together in one volume.
