The history of science reveals a number of significant shifts in the conception of the universe. Recently, 20th century physics with its new discoveries has broken away from the traditional view of the universe to seeing it as interrelated, holistic, and emergent. This version of reality is complementary with the concept of dialectics. Dialectics is defined accordingly and its flexibility is suited to guide the present eclectic stance in counselling psychology and psychotherapy. Counselling psychology and psychotherapy are discussed within Kuhn's (1970) framework of normal science, crisis, and revolution. The normal science phase demonstrates variations of the subject/object dichotomy, and active/passive therapeutic orientations. Eclecticism reflects the crisis stage. Eclecticism is a multiple perspective that does not usually guide metatheory. The revolution and resolution phase for therapeutic psychology is manifested in a new paradigm based on dialectics. Dialectics makes eclecticism legitimate and comments towards that end are presented.
