Conclusion

The potential and promise of phenomenological psychology are to advance theoretical psychology by providing it with a rigorous discourse on foundation. As history shows, this is not easily achieved. The idea of rejuvenation aims at strengthening phenomenology’s dispositions that belong to it as an original form of rationality. Rejuvenated phenomenological psychology may be able to tackle the foundational issues of psychology that express themselves as symptoms in the form of crisis, especially the problem of subject-matter, but also concerns of theory-formation and methodology. Four fields of possible growth have been identified that align with a complementarist approach, i.e., the equitable entanglement of philosophy and science.
