how can i know reality even exists?

How can I know that reality even exists if anything we think we know is just based on nuerological impulses. @ one time people KNEW the world was flat & burned people alive for suggesting otherwise. Dr. Igmund Semmelweis made groundbreaking discoveries in the medical field by discovering the reduced rate of infections that occured in medical facilities that made frequent use of antiseptics; he was the first person to theorize the existence of these tiny microscopic "bugs" that got into your body & made u sick, called "germs"; they locked him up in a nuthouse, beat him w/ in an inch of his life & he died 2 weeks later. Now, anyone who doesn't believe in germs is crazy.

    Existence or non-existence of certain shape of Earth and germs do not depend on us believing in it or not believing. Rather if these are true, we can adjust our lives appropriately, such as finding suitable treatment for different type of germs and planning constructions according to the idea that Earth is round. Otherwise we'll remain under illusion and keep trying to make necessary adjustments and deny that failure is due to wrong understanding. Until we realise that we're wrong and learn the truth.

    In each of your examples what one set of people 'knew' is contrasted with what another set did not know but suspected.

    It is not until there is a method for demonstrating that knowledge that something can be known.

    To know what is real you must define what is meant by the term reality.

    The reality that we see depends on how we perceive the world around us. Each person has his or her own perception of reality, but if reality does not exist, we would not actually be able to tell it. Therefore, reality is essential for someone to think about it.
