Immanuel Kant said, “Thoughts without content are empty, intuitions without concepts are blind.” Do you consider this a fair statement or has Kant missed something in his statement?
Yes, he has missed something. I think so much more is going on, for the human wellspring of “knowledge”. But there is an interesting point to his text (“The Critique of Pure Reason”, see below), and the simple pithy sentence should not be the harm of it—this being your question, I believe.
I examined this part of his text (LINK) only. It is the source the quote.
Kant believed that (true) reality is not understandable by the human mind. Instead, Kant believed that the mind’s mental models are the constraining structures the mind uses to perceive reality—that is, cognition is limited to whatever extent the mind possesses them, and to whatever extent that they are developed.
And, if this is an accurate representation of Kant’s theory, then I agree with it … in principle.
Now, this is what I think Kant is saying in the question’s quote,
Thoughts without content are empty, intuitions without concepts are blind.
First, a sentence before, Kant helpfully wrote:
Without sensibility no object would be given to us, without understanding no object would be thought.
So in my words, without our senses, we cannot perceive an object, and without object understanding, we could not recognize it as such.
And I agree.
But in thinking, there is so much more going on (I think).
- I do think our senses record things that our mind does not process. Yet, Kant seems to think it happens spontaneously, and both are required: “the second is the power of knowing an object through these representations (spontaneity [in the production] of concepts)”. Whereas, I think the conscious mind is involved. I think “the conscious” is a kind of thinking spotlight on selections of the incoming sensory data. With the conscious’ focus, some function of the conscious, or simple pattern matching, retrieves object representations that may represent the incoming sensory data. In other words, the mind makes the best guess possible. But it can be tricked (see optical illusion):
- When the sensory data doesn’t add up, I believe the conscious feverously attempts to cross reference other experiences (in other neural network models) in a desperate attempt to develop accurate thoughts/understandings. In this scenario, I think the conscious would narrow its focus even further to make possible rapid and accurate sensory data interpretations. Again, Kant seems to represent that understanding is spontaneous.
- The mind rejects or ignores data for which it possesses no reasonable model, and does not consider important. For example, Individuals lacking automotive experience, might likely never see or hear minor problems with their car.
- The conscious mind, with it’s consciousness spotlight, can also detect differences, or conflicts, between sensory data and the stored mental models. It is almost as if a person can set a threshold for matching so that when differences become large enough, the focus and attention of the conscious can be commandeered.
- The mind’s library is likely made of building blocks of smaller objects (neural network models), and not as integrated models complex objects. Again, the conscious focus enables the brain to assemble understandings using the smaller elements.
In the big picture however, I agree with the question’s quote. If I was permitted to substitute the vocabulary of reason into the quote:
Hypotheses without observations are empty … or, meaningless. Observations without hypotheses are blind … or, understanding dead ends.
And I love that.
