“But he isn’t wearing anything at all!”
“Did you hear the voice of that child!” someone cried. The child’s remark was whispered from one person to the next.
“The Emperor is not wearing any clothes!”
“The Emperor is not wearing any clothes!”
“He isn’t wearing anything at all!” the crowd shouted.
The Emperor cringed, for he was beginning to suspect that everyone was right. But then he realized: “I must go through with it now, parade and all.” And he drew himself up more proudly than before and continued to walk ...wearing no clothes.
-- The Emperor's New Clothes, Hans Christian Andersen

Sometimes it takes a young one to shout the truth. Do we entertain their exclamations?

"It's not what it seems! "
"You have got it all wrong!:
"They(the dragons) are not what you think they are!"

Is it because we think we have more logical thinking than them(the younger)?
If you believe that seeing is believing, are we willing to see? Or do we keep our eyes closed? Is there not a possibility that we are blinded by something? If we don't see it, does it mean that it is not valid/untrue? Must we see to know/believe?

"Now Thomas (called Didymus), one of the Twelve, was not with the disciples when Jesus came. So the other disciples told him, "We have seen the Lord!" But he said to them, "Unless I see the nail marks in his hands and put my finger where the nails were, and put my hand into his side, I will not believe it."

A week later his disciples were in the house again, and Thomas was with them. Though the doors were locked, Jesus came and stood among them and said, "Peace be with you!" Then he said to Thomas, "Put your finger here; see my hands. Reach out your hand and put it into my side. Stop doubting and believe."

Thomas said to him, "My Lord and my God!"
Then Jesus told him, "Because you have seen me, you have believed; blessed are those who have not seen and yet have believed." (John 20:24-29)
