Knowledge is what makes us different from others animals, because it all deals with our mind and soul only – it's nothing concrete, even though some jobs are based on it; it's nothing to be eaten/drunk or to sleep in or to cover with, but we just aren't humans without it. Of course it's a choice, not a duty, everyone is completely free to decide not to have knowledge (that's one of the meanings of freedom); however never forget people's ignorance is weakness to people theirslves and power to overbearing potents.

I completely agree! Without knowledge, how can the human race continue to evolve? That's why we are here...to learn and teach the next generation

in my opinion,knowledge is very important in our lives.it can make our lives more colorful and wenderful. the knowdge ,if we don't understand it,we will loss much fun.

I heared that we can find the answer in the book ,but i think it should be say :we can find answer in the knowledge . esecially when we are at a complete loss what to do.we can know what we need in our life in the knowledge
