Quote by Karl Wilhelm Von Humboldt
The sensual and spiritual are linked together by a mysterious bond, sensed by our emotions, though hidden from our eyes. To this double nature of the visible and invisible world -- to the profound longing for the latter, coupled with the feeling of the sweet necessity for the former, we owe all sound and logical systems of philosophy, truly based on the immutable principles of our nature, just as from the same source arise the most senseless enthusiasms.
Summary
This quote suggests that there is a complex connection between the sensual (related to physical experiences) and the spiritual (related to the non-physical or metaphysical realm). Our emotions are able to perceive this connection, even though it remains unseen. It argues that our deepest desires and needs fluctuate between these two realms, which gives rise to both rational philosophies grounded in human nature and irrational enthusiasm. It implies that the balance or interplay between these two aspects shapes human experiences and drives our understanding of the world.
