This is a question that has often been asked, appended by a statement that scientists can do it. Not all, but to a great extent it is true; scientists from all over the world have working relationships with each other, share information and build upon what others have accomplished. Military experts have also shown capability to do so, and perhaps even some diplomats. So why can’t we all do the same? In a word, it all has to do with respect.
Respect for what? knowledge, intelligence, flexibility, technical competence. Yes, self-interest plays a part; they need each other because they know they can learn from each other; and the rest of us don’t? World players such as these that have capabilities and competence that are admired – and respected – are in great demand for collaboration, and they collaborate because they know that teamwork accomplishes more than confrontation, and have common interests that transcend petty jealousies (not always, but more than is common elsewhere). Ok, until egos get in the way. The same is often true of athletes, artists and even performers.
So why can’t all the rest of us do it? For the reverse of the reason that they can: lack of respect. Sure, there are cultural differences, language differences, lack of mutual understanding, and even fear; but I would contend that roll those up and you come up with lack of respect for them, and who they are, or who it is perceived they are. Be clear, however, that respect is a two way street, so the basis is actually MUTUAL RESPECT. Respect, after all, is much like affection; we like people who like us; we respect people who respect us; and often the cause of lack of respect builds on ignorance or hatred or prejudice.
But the answer to the question why can’t we all just live together is that it will not happen until there is mutual respect, regardless of why there is a lack of it; and to have mutual respect we must have reason, and want to, which many (most?) just don’t. Think about it, and think about why scientists can work together and most of the rest of us cannot: they have grounds for respecting each other that transcend all those differences which the rest of us lack, for whatever reason, and until all of us deserve respect from each other – mutually – it cannot happen.
