The advocate plays an intermediary role between nature (which is non-linguistic) and humanity (which defines itself as quintessential linguistic), interpreting a variety of non-linguistic "meanings" in natural phenomenon which he or she then translates into language, often with didactic overtones. This intuitive and experiential perspective of the material world is markedly different than the "objective" approach privileged within the dominant culture. The advocate rejects the strict dichotomy between objective and subjective ways of knowing, suggesting instead that knowledge is transactional
