We can imagine flying like a bird and can do so through airplane or other means of flying. But if one does not do anything with his/her imagination, nothing will happen. Indeed, we can realize our imagination variously. But how to realize it is crucial. If one goes up a mountain and jumps off from a cliff or mountaintop, that person will be killed in a few seconds. This kind of imagination is so naïve that even one’s life may be lost. But if a person invents new things to ride on or uses a hang glider, he/she can fly like a bird. Thus what we need is imaginative power combined with critical, self-critical thinking.
