"Many things, for aught I know, may exist, whereof neither I nor any other man hath or can have any idea or notion whatsoever"

This quote by George Berkeley is a suggestion that there is much on the planet that we do not understand. It suggests that there are things that exist that we might not be aware of, and that our knowledge is restricted. It is a pointer that we must be open to the possibility that there are things that we do not comprehend, and that we should not be so quick to dismiss something as difficult. It is a pointer that we need to be simple in our understanding of the world, and that we need to want to accept that there may be things that we do not know. It is a tip that we must be open to new ideas and possibilities, and that we should not be so fast to dismiss something as impossible. It is a tip that we ought to be willing to explore the unidentified, which we must not be so fast to dismiss something as difficult.
