Emotions are the basis of all knowledge.

I have an actual argument today for why I disagree with that all knowledge comes from emotion. In Biology we learn that chemicals and hormones in our bodies are what cause emotions. To me hearing that emotions are caused and are a result of chemicals in our blood translates from the original statement that knowledge is simply chemical releases in our bodies. Now this might work in some ways, that knowledge comes from within us and that every human being has the potential for knowledge in everything if it comes from those chemicals but i believe humans are more than primal animals that live off of instinct. I believe that the ability we have to reason and see past the ordinary to learn and discover and research means that a basic hormone release will not have that much of an influence on our knowledge. If knowledge is justified True belief, maybe i will be more motivated to research something but even if i have no emotional response to something or less of one than someone else i will still have knowledge. Maybe i won't have as much understanding as that person since they were motivated but I have knowledge anyways. Therefor we can say that emotion brings on knowledge because there are areas of study that happen because of other workings in our brain. Emotion does play a part but does not play the main part. The main part of learning in my opinion is a combination of language, reasoning and perception with little emotion in some subjects and more in others.
Just my opinion.
