When I was a child, I spoke like a child, thought like a child, and reasoned like a child.
When I became a man, I gave up my childish ways.
There's a great anecdote, about how Alec Guinness met a young boy that claimed he had seen Star Wars over a hundred times. Guinness, a smart man, realizing that Star Wars was just a fairytale, or more cruelly a tale of "secondhand, childish banalities", tried to make the child promise him to never again watch Star Wars.
