"The most elusive knowledge is self-knowledge, and it is usually acquired through solitude, rather than through interaction with others."

Knowledge is an aspect that is highly extended and it is changing always through the time. Hence, when we are discussing about knowledge, it not a simple issue at all. It maybe possible that we could enlarge and learn most parts of the knowledge by ourselves however we inavetabily will need to interact with others to utilize their experiences and knowledg. Hence, the knowledge can be learnt both by self-knowledging and communication with others.

There are a vast number of factors that they are needed in the educational process; effort, investigation, questioning and etc are such these factors. When you are resolute to learn a specific part of knowledge, at first, you have to do reseachs and investigations in that part. In this way, you need to make all your effort that can acheive your goal which is learning knowledge. For getting your knowledge more powerful and because you want to expand it, you must be active exactly like a scientist and do numerous questioning, researches and effort. Hence, it can be inferred that the self-knowledge is the foremost part of learning.

In the contrary, you may have not this capability that could do all kind of reseaches to be educated; due to your ability of thinking and your capability of solving problems is limited. In fact, all the human race has some kinds of limitations. Hence, any one cannot claim that he/she is complete. Therefore, we surely will need to others that could help us in this case. We can use from their experience, knowledge, consulting and etc. for instance, when you have got stuck in a mathematical problem and you are uncapable to solve it, you obviously will need to be guided by a person who has more experience and knowledge in the problem. So, you will ask your instuctor to resolve your problem. Therefore, we are not free of others experience and knowledge and in some cases, we will surely need their directions.

As a summary, it is true that the most elusive knowledge is self knowledge and it is usually acquired through solitude, however, we need interaction with others that could enhance our knowledge and experience.
