Here are a few quotes of Gene Roddenberry (creator and writer for the Star Trek series) on what Star Trek means . . .
1. “Star Trek was an attempt to say that humanity will reach maturity and wisdom on the day that it begins not just to tolerate, but take a special delight in differences in ideas and differences in life forms.”
2. “To be different is not necessarily to be ugly; to have a different idea is not necessarily to be wrong. The worst possible thing is for all of us to begin to look and talk and act and think alike.”
3. “If we cannot learn to actually enjoy those small differences, to take a positive delight in those small differences between our own kind, here on this planet, then we do not deserve to go out into space and meet the diversity that is almost certainly out there.”
4. “If man is to survive, he will have learned to take a delight in the essential differences between men and between cultures. He will learn that differences in ideas and attitudes are a delight, part of life’s exciting variety, not something to fear.”
5. “Science knows still practically nothing about the real nature of matter, energy, dimension, or time; and even less about those remarkable things called life and thought. But whatever the meaning and purpose of this universe, you are a legitimate part of it.”
6. “I believe in humanity. We are an incredible species. We’re still just a child creature, we’re still being nasty to each other. And all children go through those phases. We’re growing up, we’re moving into adolescence now. When we grow up – man, we’re going to be something!”
