Quotes from the same author

One has only as much morality as one has philosophy and poetry.
 Karl Wilhelm Friedrich Schlegel
Since poetry is infinitely valuable, I do not understand why it should be more valuable than this or that which is also infinitelyvaluable. There are artists who perhaps do not think art to be too great, for this is impossible, and yet they are not free enough to be able to rise above their own best accomplishments.
 Karl Wilhelm Friedrich Schlegel

 Karl Wilhelm Friedrich Schlegel
A genuinely free and educated man should be able to tune himself, as one tunes a musical instrument, absolutely arbitrarily, at his convenience at any time and to any degree, philosophically or philologically, critically or poetically, historically or rhetorically, in ancient or modern form.
 Karl Wilhelm Friedrich Schlegel
