Description/Abstract

My answer to the question in the title is "No". In support of this point of view, we analyze some examples of saddle-point methods, especially as applied to quantum "tunneling" in nonrelativistic particle mechanics and in cosmology. Along the way we explore some of the interrelationships among different ways of thinking about path-integrals and saddle-point approximations to them.

plainTeX, 21 pages, 1 figure (in color). Correction made to eq. 6: a previous version erroneously gave Re(f(z)) rather than Im(f(z)). (Thanks to Adam Brown for this correction.) Most current version is available at this http URL (or wherever my home-page may be). To appear in {\it Recent Research in Quantum Gravity}, ed. A. Dasgupta
