What is the draw that these stories have on us, with characters that feel so much like friends? Gene Roddenberry originally intended the show to be a "wagon train to the stars", which I believe it was successful at accomplishing. It is an adventure in the final frontier, a story told with such strength of purpose, finding such a joy in the human condition and in how we strive forth.
The ancient Nordic and Teutonic societies originally worshipped Tyr as the leader of the gods. A god of war, warriors, and destruction was so very appropriate in their culture. Yet over the course of time their leaders and shamans brought forth the god Odin/Wodan. Odin was overwhelmingly dedicated to the pursuit of knowledge and wisdom. He hanged himself from Yggdrasil, the World Tree, for the sake of knowledge; traded his eye to the Norns for the sake of knowledge; and sent out his ravens Huginn and Muninn day after day to return to him with knowledge. Yet Odin was still a warrior god, vengeful and powerful.
Space, the final frontier. That which is beyond us.
To explore. To know.
To boldly go. With strength.
Where noone has gone before. The unknown.
