There is a distinction, but no opposition, between theory and practice. Each to a certain extent supposes the other. Theory is dependent on practice; practice must have preceded theory.
Theory without practice is of little value, whereas practice is the proof of theory.Theory is the knowledge, practice the ability.
The standard theory may survive as a part of the ultimate theory, or it may turn out to be fundamentally wrong. In either case, it will have been an important way-station, and the next theory will have to be better.

Critical reflection on practice is a requirement of the relationship between theory and practice. Otherwise theory becomes simply "blah, blah, blah, " and practice, pure activism.
Those who are in love with practice without knowledge are like the sailor who gets into a ship without rudder or compass and who never can be certain whether he is going. Practice must always be founded on sound theory, and to this Perspective is the guide and the gateway; and without this nothing can be done well in the matter of drawing.
..if the beginning of the thought or theory is not rooted in reality, the end or the final results of such a thought or theory could well be disastrous in practice.

Lucky accidents seldom happen to writers who don't work. You will find that you may rewrite and rewrite a poem and it never seems quite right. Then a much better poem may come rather fast and you wonder why you bothered with all that work on the earlier poem. Actually, the hard work you do on one poem is put in on all poems. The hard work on the first poem is responsible for the sudden ease of the second. If you just sit around waiting for the easy ones, nothing will come. Get to work.
