Final answer:
The phrase "believing is seeing" conveys that our beliefs shape our perception of reality, which is illustrated in the 'Prisoners of Silence' video through the allegory of prisoners in a cave who only see shadows and must revise their beliefs upon experiencing the outside world.
Step-by-step explanation:
The phrase "believing is seeing" suggests that what we believe influences our perception of reality. In the context of the 'Prisoners of Silence' video, it is demonstrated through the allegory of prisoners who are chained in a cave and can only see the shadows of objects, leading them to believe that the shadows are the full extent of reality. It is only when a prisoner is freed and experiences the outside world that he realizes his previous beliefs were mistaken and starts to see the world as it truly is. This allegory can be likened to people who are influenced by a limited or biased perception of reality based on their experiences and those around them, such as the child raised in a commune with racist ideologies. Their 'seeing' is directly influenced by their 'believing', and only by challenging and expanding their beliefs can they see a broader truth.
