"Man seeks objectives that enable him to convert the attainment of every goal into a means for the attainment of a new and more desirable goal. The ultimate objective in such a sequence cannot be obtainable; otherwise its attainment would put an end to the process. An end that satisfies these conditions is an ideal... Thus the formulation and pursuit of ideals is a means by which to put meaning and significance into his life and into the history of which he is part."
