“We must begin by acquiring the discipline that modern science can teach us. 
We must school ourselves in this way and then, taking the strict methodology,
 the scientific discipline we have learned from modern natural science, 
transcend it, so that we use the same exacting approach to rise into higher
 regions, thereby extending this methodology to the investigation of entirely 
different realms as well.” —Rudolf Steiner

If only sensory phenomena are within the reach of scientific research, the
 doors are closed to those worlds from which the human being originates 
and where the creative forces of the world are found. Rudolf Steiner challenges
 us to develop organs of perception needed to go beyond these limits of 
perception, so that we can witness the spirit that is active in all natural phenomena.
