Thinking

Talking with oneself... hence also inwardly listening.
I agree with this quote because thinking involves talking and listening to yourself. You need to talk to yourself otherwise you wont know what you are thinking and you need to listen to absorb the information. I also disagree because if you are sitting there talking to yourself you probably would feel a little stupid. I think that when they say talking they actually mean considering the information that you are taking in. After you decide if the information is worth taking in then you listen to it in your head so you can remember it and understand what it actually means. You then take that knowledge that you have gained and apply it to everyday life. If you dont repeat the information to yourself you probably wont remember it so it would be useless. Then after you repeat it to yourself you should hear it in your head and record it to your memory and understand its true meaning.
