Is the collaboration of phenomenology with non philosophical (particularly empirical) scientific disciplines an opportunity for phenomenology to de¬velop its potential and show its vitality, or does it rather constitute a risk, or even perhaps an unjustifiable excess and abandonment of its most essential methodological principles? Contemporary and classical phenomenologists do not adopt a united stance to this question. The Czech philosophical milieu typically treats this problem in a black and white framework: the collabora¬tion of phenomenology with other scientific disciplines is presented either as unproductive, even meaning less, or it is thought of as possible, desirable and full of promise. The main aim of this study is to present several distinc¬tions which are designed to provide a more supple and complex approach to the question of determining the correct possibilities and limits of the inter¬disciplinary collaboration of phenomenological philosophy.
