An attempt at a macrorealistic quantum worldview

Many scientists agree that various difficulties arise when one tries to build up a worldview incorporating some form of realism which can accommodate our knowledge about natural phenomena. We investigate whether quantum mechanics (Q.M.), in the standard interpretation or in some of its more widely known and accepted variants, can be taken as a basis for such a program. Having pointed out that, in our opinion, this is not the case, we present an attempt to overcome the difficulties by accepting stochastic and nonlinear modifications of the evolution equation of the theory.
