As similarly noted by Socrates, the presence of knowledge does not encourage one to seek out the information further for they have already grasped the subject. This shows how perplexity is crucial to broadening the scope of knowledge because it extends the lengths by which one wishes to obtain knowledge as well. People can resolve this mode of confusion or unknowing by experience, a more direct way of obtaining the missing information, or by teaching, where the information is directly taught to them in the hopes of being able to retain said information.
In conclusion, perplexity is central to learning or knowing because it influences the student to bridge the gap and conduct the research or search for the resources to find the information they need. Without this perplexity, there leads a life of finite knowns, thus placing a limit on the amount of future knowledge gained.
