Is Seeing Believing?

Some of our knowledge is gained through sense perception, when we ask the question 'is seeing believing,' we have to look at the question of how reliable are our perceptions? People believe that what they have seen is what is true, however, this is not always true. As human beings, we tend to 'fill in the gaps', therefore we might think we have seen something but other factors may have influenced it which does not make it necessarily 'real', it might be true to you but in reality it is not. Sometimes when we are so desperate to see something, we will convince ourselves that that is in fact true. Our perceptions are not always 100% reliable as what we perceive is affected by our environment and who we are.
