(Proverbs 7:6 KJV) For at the window of my house I looked through my casement,
We are to be observers of the world around us and see it as it is. This takes some work and honesty on our part. In the previous verses the looker has the benefit of the teaching of wisdom. Obviously he was listening. That helps him to see reality.
In the following verses he recognizes that the people he is seeing are very shallow. The young man he will observe is even simpler than the average. He will also watch the young man for a brief time and know where he is going and what he will be doing.
Wisdom can give us the foundation to make observations of our world. It can help us see things as they are. There is a saying about how many people can learn from their own mistakes but only a few can learn from the mistakes of others. We are expected to be in that few.
So? Build your foundations. You never know when you will be required to make decisions based on partial observation. You may never know all the facts but you can know the basic principles.
