In this work the distinguished physical chemist and philosopher, 
    Michael Polanyi, demonstrates that the scientist’s 
    personal participation in his knowledge, 
    in both its discovery and its validation, 
    is an indispensable part of science itself. 
    Even in the exact sciences, “knowing” is an art, 
    of which the skill of the knower, 
    guided by his personal commitment and his passionate sense 
    of increasing contact with reality, is a logically necessary part. 
    In the biological and social sciences this becomes even more evident. 
                
  
    The tendency to make knowledge impersonal in our culture 
    has split fact from value, science from humanity. 
    Polanyi wishes to substitute for the objective, 
    impersonal ideal of scientific detachment an alternative ideal 
    which gives attention to the personal involvement of the knower 
    in all acts of understanding. 
    His book should help to restore science to its rightful place 
    in an integrated culture, as part of the whole person’s continuing 
    endeavor to make sense of the totality of his experience.
