phenomena that go beyond these are excluded from 

 science. 



It is important to reahze, what is often forgotten,

 must keep in mind in judging the attempts of men of 

 science to portray the nature of reality or of the uni-

 world as a true and complete picture. Only if the field 

 of science is taken to include all experience can science 

 aspire to present an adequate picture of the world.

 data obtained by observing other individuals and 

 things, but also those that we reach through the fact

 that brings forth these things. The universe is a sys-
