| I want to divide human understanding into two kinds—classical understanding and romantic understanding. In terms of ultimate truth, a distinction of this sort has little meaning, but it is quite legitimate when one is operating within the classic mode used to discover or create a world of underlying form. The terms classical and romantic, as Phaedrus used them, mean the following: A classical understanding sees the world primarily as underlying form itself. A romantic understanding sees it primarily in terms of immediate appearance. If you were to show an engine or a mechanical drawing or electronic scheme to a romantic, it is unlikely he would see much of interest in it. It has no appeal because the reality he sees is its surface. Dull, complex lists of names, lines and numbers. Nothing interesting. But if you were to show the same blueprint or give the same description to a classical person, he might look at it and then become fascinated by it because he sees that within the lines and shapes and symbols is a tremendous richness of underlying form. The romantic mode is primarily inspirational, imaginative, creative, intuitive. Feelings rather than facts predominate. "Art" when it is opposed to "Science" is often romantic. It does not proceed by reason or by laws. It proceeds by feeling, intuition and esthetic conscience. In the northern European cultures the romantic mode is usually associated with femininity, but this is certainly not a necessary association. The classic mode, by contrast, proceeds by reason and by laws—which are themselves underlying forms of thought and behavior. In the European cultures it is primarily a masculine mode and the fields of science, law and medicine are unattractive to women largely for this reason. Although motorcycle riding is romantic, motorcycle repair and maintenance are purely classic. The dirt gives it such a negative romantic appeal that women never go near it. |
