last day and when i was in the middle of a conversation with two of my friends i asked a question .
one of them started his opinion with "i see" and the other with " i believe" .that is make me think 
what is the difference between what we think and what we see? probably you will say "nothing"or "what a silly question?"  i am telling you it is a lot more than nothing and not silly at all .
from my point of view :
the first answer {i see}built on feeling and hinge on the place and the time 
the other one " i believe" built on thinking and do not hinge on a place or a time you can say it is a principle.
i repeat again that is from my point of view.
