While the unity versus division theme isn’t well developed, I love how Star Trek Beyond explores psychological meaning and purpose.
The film begins with Kirk feeling as though life has become “a little episodic”. Both he and Spock are struggling with their decision to enlist in Starfleet and are debating if this path still makes sense for them. As the Enterprise is destroyed, and the characters lose the thing that kept them together, each character has to find themselves, each other, and rediscover what they really care about in life.
Something we’ve discovered from positive psychology is how important meaning is to our long-term happiness. Meaning is about contributing to something that is greater than yourself. Some develop meaning through family, a career, service to a community, belief in a religion, or by advancing a cause. Being connected to a purpose doesn’t always make you feel better, but it does help you endure hardships. Viktor Frankl said it best in Man’s Search for Meaning: “Those who have a 'why' to live, can bear with almost any 'how'.” This is the reason finding renewed purpose in your work is a great way to cope with a job you don't like.
Like Kirk in Star Trek Beyond, at some point we all feel like life has become a constant rerun of the same events. That’s because of habituation/hedonic adaptation – we get used to things that remain the same. Your new job is exciting for a while, but eventually it’ll feel like a boring routine. We also don’t form many new memories when we do the same thing every day, which is why time flies as we get older. Connecting with something that gives our lives purpose, something that will continue when we're gone, that’s what helps us overcome these ruts.
That’s exactly what Kirk and crew do in Star Trek Beyond – each discovers that it’s not the exploration of the final frontier that give their lives purpose, at least not anymore. It’s the journey they're taking together, their friendship, their love for one another, the family they have formed that really matters now.
That's a far better tribute to Star Trek than a simple message about unity versus division.
