 There is, then, this deep division within the philosophy of the Scottish Enlightenment, yet it occurs within a context of striking unanimity also. “Wise men now agree, or ought to agree in this, that there is but one way to the knowledge of nature's works; the way of observation and experiment” Reid writes (Reid 1764, 11), thereby endorsing the express intention of Hume to “introduce the experimental method of reasoning into moral subjects” (the subtitle of the Treatise). Both remarks reflect a commitment to the project of a “science of mind”, a project common to all the major Scottish philosophers of the period. Thus George Turnbull (Reid's teacher) writing in 1740 says “I was led long ago to apply myself to the study of the human mind in the same way as to that of the human body” (quoted in Davie 1994, 24)
