"Nail's view of the object can be characterized as “change is the only constant" (to quote those who have gone before). Nail (Univ. of Denver) sets out to convince readers that reality is not a stable essentialist subject/object dichotomy but rather a materialist process of kinetic historical progression. (...) That said, Nail's writing style is generally approachable, so even readers not drawn to academic philosophy of science might find this an interesting read."
