Something "makes sense" only in the context of what is known and familiar to us. Television, for example, makes sense to us because we have all grown up with it and most of us have at least a rudimentary understanding of the concepts of electricity and television waves. If you tried to explain television to a person living in the 15th century however, he would look at you as if you were insane and would probably lock you up for heresy to boot.

Every generation seems to suffer from the belief that we know all there is to know. This is actually a form of mass psychosis and leads to all sorts of problems. The greatest thinkers and innovators are those with a firm understanding that we should never be bound by what "makes sense."

There is a form of meditation used in Chabad Chassidus called hitbonenut. Hitbonenut takes the notion that "faith begins where the intellect ends" to its logical conclusion.

In this form of meditation, we start to analyze a concept, such as television, in such depth that we begin to grasp the root and foundation of the theories underlying it, all their implications, and how they relate to other aspects of reality. We get to a place where we can truthfully explain how television works to a four year-old child. Then we challenge ourselves to keep pushing deeper and higher, even past the limits of our intellects until we get to a point of weeping because we have arrived at a place that can only be experienced, but not explained (or held onto). It is the place where the intellect ends and nothing makes sense because we cannot relate to it.

This is a taste of the En Sof (G‑d without end) and it can fuel our faith for a lifetime. Hitbonenut allows us to experience a reality that lies outside our normal lives where "what makes sense" has no foothold. It shows us how our lives can become so much bigger if we can let go of the notion that something needs to make sense to be true.
