There would be a world, but few people. I say 'few' because you can reproduce without love, but not many do...
Equilibrium... If you havn't seen that movie then get your ass off the computer and go rent it. It's just that good!
love is just a word defining a concept and the concept is just a theory, one which seems to work in this day and age, but it's not like we would know what it was if we didn't think it existed, so it truly wouldn't matter much, either way, technically, but, what would the world be without it.
Now that I think of it, no there wouldn't.... Man see woman, man kill woman... Man see woman, woman kill man... Man rape woman, woman kill child No love no nothing
It would be different than that, in the way I was putting it into context, which was if we didn't know love existed.
Impossible, you cannot deny love from the world without denying the world of all other emotition in which case we would be robots, we would live to carry on our existance, we would not kill each other as there would be no point, you feel nothing for the person, not love or hate.
