It is argued that the correct answer to the three questions in the title is "no": that the theses being denied derive from traditional philosophy, not from the way the quantum theories are used. For example, the calculation of the energy spectrum of an atom assumes the autonomous existence of the atom, rather than its dependence upon the observer. However, it is also suggested that the problem has been unnecessarily complicated by a careless use of the terms "realism," "materialism," and "determinism." Precise definitions of these words are proposed.
