Rudolf Steiner developed exercises aimed at cultivating new cognitive faculties he believed would be appropriate to contemporary individual and cultural development. According to Steiner's view of history, in earlier periods people were capable of direct spiritual perceptions, or clairvoyance, but not yet of rational thought; more recently, rationality has been developed at the cost of spiritual perception, leading to the alienation characteristic of modernity. Steiner proposed that humanity now has the task of synthesizing the rational and contemplative/spiritual components of cognition, whereby spiritual perception would be awakened through intensifying thinking. He considered this relevant not only to personal development, but as a foundation for advanced scientific research.
