Our ability to wonder..

"It seems as if in the process of growing up we lose the ability to wonder about the world." -Albert Knox.

Personally, I do not agree with Knox and do not think that one can "lose the ability to wonder". It is just that as we grow older, we become more adapted to the expectations of society and more accepting towards reality.
Infants have unlimited access to new experiences, therefore question experiences and learn through them. However, as we grow older, we realise what really is the truth and what we are expected to believe, thus leaving us less room to wonder about things. We accept the truth as it is stated, without challenging it or giving it a second chance to be thought about. This does not necessarily mean that we have LOST our ability to wonder; this just means that we have only put it aside and believed what we perceive to be the truth (basically, what everyone else or the majority thinks is correct). For example, when baby Thomas sees his dad floating, he does not regard this as being abnormal, and accepts it. However, his mother, being used to the fact about gravity and not being able to fly, gets scared and freaks out. Instead of wondering why and asking how the dad is floating, she thinks "that should not be happening."
Growing up also means daily routine, meaning more things to do and less time to wonder. Having less time to wonder means we have less time to think about why we do things and for what reason we do them for. However, as I mentioned above, because the ability to wonder is not completely lost, when we take a minute to think about the things that have happened, it is most likely that we will wonder why those things have taken place at that time, and for what reason.
So, in my opinion, I do not think that we have not LOST the ability to wonder. It is just that we do it less as we grow older.
