To trace the development of mind from earliest times ... requires ... not a categorical concept, but a functional one.... The most promising operational principle for this purpose is the principle of individuation.

The historian does not locate known facts in a hypothetical, general pattern of processes; his aim is to link fact to fact, one unique knowable event to another individual one that begot it.

A signal is comprehended if it serves to make us notice the object or situation it bespeaks. A symbol is understood when we conceive the idea it presents.

Artistic form is congruent with the dynamic forms of our direct sensuous, mental, and emotional life; works of art are projections of "felt life", as Henry James called it, into spatial, temporal, and poetic structures.

Every artistic form reflects the dynamism that is constantly building up the life of feeling.

The arts objectify subjective reality, and subjectify outward experience of nature. Art education is the education of feeling, and a society that neglects it gives itself up to formless emotion. Bad art is corruption of feeling.

Philosophical questions are not by their nature insoluble. They are, indeed, radically different from scientific questions, because they concern the implications and other interrelations of ideas, not the order of physical events; their answers are interpretations instead of factual reports, and their function is to increase not our knowledge of nature, but our understanding of what we know.
