"This situation of the complication and the order to function of an organism, where the sum is greater than its parts (i.e. has a higher order), becomes more astonishing every year as the scientific results become more detailed. Because of this, many scientists are now driven to faith by their very work. In the final analysis it is a faith made stronger through the argument by design. I simply do not now believe that the reductionalist philosophy, so necessary to pursue the scientific method and, to repeat, the method which all scientists must master and practice with all their might and skill in their laboratory, can explain everything". Allan Sandage, eminent astronomer and born-again Christian in the late 20th century
