Why has modern philosophy con- tributed so little to bring about an integration between what we know about the world and the intelligent direction of what we do? The purport of this chapter is to show that the cause resides in unwillingness to surrender two ideas formulated in conditions which both intellectually and practically were very different from those in which we now live. These two ideas, to repeat, are that knowledge is concerned with disclosure of the characteristics of antecedent existences and essences, and that the properties of value found therein provide the authoritative standards for the conduct of life.
