In the context of speaking about human teaching and its teachers (Mathew 15:8, 9) Jesus said: “They are blind guides. If the blind lead the blind, both will fall into a pit.” (Mathew 15:14)
Its application need not be too limited because what is being subjected to our senses is very limited. Even with regard to our own body, we have a limited vision. It’s like seeing only the tip of our nose because our bodies are continuously being recycled with even 98% of all our atoms being replaced in less than a year. Heraclitus stated that one can’t step into the same river twice because there is constant change occurring. There is always something preceding to something which means there cannot be a beginning for anything—even for universe. Not seeing this endless aspect would amount to blindness.
