During the 1960s and 1970s, the Theory Movement in Nursing

During the 1960s and 1970s, the theory movement in nursing sought to "prove" that nursing was a science by applying strict logical positivist philosophy to the discipline. Why was this application problematic from a philosophical standpoint?

A) It placed too great an emphasis on the art of nursing and left itself open to criticism by the postmodern school of philosophy.
B) It ignored the humanistic and social aspects of providing quality care and focused on the hard science involved.
C) It took too long to develop and by the time it came to fruition the logical positivist perspective had fallen out of favor with most scientific disciplines.
D) It was later disproved by feminist philosophers who unequivocally demonstrated that the logical positivist view was heavily biased against women and minorities.
