Easter Slogans

This Easter my 4 year old granddaughter went to church with her parents and little sister. Hailey agreed to go to Sunday school and afterwards Kendra, my daughter, asked her what they had done. Hailey said that they had let some balloons go into the sky while they were all saying three words. Kendra asked what the three words were. Hailey thought a moment and said: "He's In Prison."

What is Truth?

I used to view myself as having a pretty good grasp of reality. This picture disabused me of that.

I didn’t believe its claim that the squares marked A and B are the same shade of gray. I printed out the image. I still didn’t believe it. I cut out the A and B squares and brought them together—they match.


Below are the two squares cut out with Microsoft paint







Since my perceptions are clearly wrong with a simple image, I don’t think I should be confident that my perceptions on other things (like people) are accurate. Clearly, when senses and human frailties are involved truth can be elusive.
