Generally speaking, the senses are not the best sources of information. They are not sharp enough, they tend to oversee and ignore important information, they can be conned easily, and they tend to exaggerate and imagine things. Worst of all, they also lie deliberately.

For example, when you watch a movie the eyes bring the information about the movement on the screen to the brain. In fact, 'movies' are still pictures that are moved at the rate of thirty-two per second, and this slow pace is enough to con the eye. In a similar manner, all of the first five senses are far from being reliable.

The sixth sense, the sense of mind impressions, is the worst of them all. It is delusional, it has tendencies towards hysteria, and it confuses hallucinations with reality on a regular basis. The CNS, however, relies on this as much as it does the other senses.

The 'General' in his secluded bunker, ie: our Central Nervous System, has only these communication officers to rely upon. Blind as he is, the General 'believes' and interprets the information received by the senses as true and valuable. The General then takes immediate action on the basis of this interpretation!

It should be made clear that, unlike the senses, the General very rarely makes mistakes. It can be said with great confidence that the General always does the right thing. However the General is fighting against an enemy he doesn't see. He distributes commands to deal with reality not as it actually is, but rather how the senses have described it to him.
