“Experience without theory is blind, but theory without experience is mere intellectual play.”
This is declared to be "an old Kantian maxim" in General Systems Vol. 7-8 (1962), p. 11, by the Society for the Advancement of General Systems Theory, but may simply be a paraphrase or summation of Kantian ideas.
Kant's treatment of the transcendental logic in the First Critique contains a portion, of which this quote may be an ambiguously worded paraphrase. Kant, claiming that both reason and the senses are essential to the formation of our understanding of the world, writes: "Without sensibility no object would be given to us, and without understanding none would be thought. Thoughts without content are empty, intuitions without concepts are blind (A51/B75)".

Context: I do not ascribe to God ignorance of anything or any kind of weakness; I hold that Divine Providence is related and closely connected with the intellect, because Providence can only proceed from an intelligent being, from a being that is itself the most perfect Intellect. Those creatures, therefore, which receive part of that intellectual influence, will become subject to the action of Providence in the same proportion as they are acted upon by the intellect. This theory is in accordance with reason and with the teaching of the Scripture, whilst the other theories previously mentioned either exaggerate Divine Providence of detract from it.

“Blind commitment to a theory is not an intellectual virtue: it is an intellectual crime.
