Some philosophers legitimate their claims about mind by citing the evidence of cognitive psychologists; some cognitive psychologists seek legitimacy in the discoveries of the neuroscientists; some neuroscientists look for support in the research of of molecular biologists; some molecular biologists explain the electrical activity of neurons with the concepts of the physicsts; and all stand gazing in awe at the mathematicians, who, staring straight ahead, worry occassionally about the shaky foundations of their elegant equations. The members of each scientific discipline, like children trying to join a more powerful group, seek to persuade others by announcing who their friends are.
