Gestalt psychologists have pointed out the interesting tendency of human brain to fill in the blanks in order to achieve an understanding of the world or sense data. Humans are incessant interpreters. They are all the time trying to figure out what something means.
This quest and inclination has a helpful hand in enabling man to make a sense of things he cannot understand. He inputs data from his own previous experiences into otherwise seemingly meaningless data. Man is a puzzle solver and his attempt through hypothesizing and associating data with other data has given rise to a plethora of philosophies and ideologies. Especially, when the conjectures appear to be pragmatic and working well, the interpretations usually become sealed for posterity until someone is able to find a loophole in it.
The negative aspect of this inclination could be false suspicion and negative doubt. This process has been illustrated in many a novel and play of tragedy in literature. It also follows from a desire to make a sense of things happening; however, bad data and a wrong process of reckoning lead to false conclusions.
This is even more important in the context of spiritual faith. The spiritual man compares spiritual matters with spiritual matters. The natural man is not able to make any sense out of spiritual things. The Bible does not encourage blind faith; however, without faith one cannot even know God at all.
