„Die Medizin ist von Haus aus eine praktische Disziplin; sie ist weder eine Natur – noch eine Sozialwissenschaft; ihre Intention geht nicht darauf, ein Stück natürlicher oder sozialer Wirklichkeit zu erkennen, sondern darauf, in dieser Wirklichkeit bewußt und geplant zu handeln.“

„Modern sciences has no place for the study of our subjective experience, yet science relies on perceptions of the world. To resolve the paradox and understand consciousness, we need to establish a new kind of ‚qualitative science‘. One difficulty has long beset neurophysiology and psychology: there appears to be no place in the brain for conscious or mind.

This conundrum has led many scientists to conclude that mind does not exist as a separate entity. Psychology and psychiatry suffer from this exclusion: they lack a theoretical framework in which to explain and investigate consciousness.“ ...

„These two views, one through the primary qualities (physics) and the other through the secondary qualities (subjective experience) might then be related to make a unified whole. Brains could then become conscious.“
