why is it that we (as humans) cannot stand to be alone?

Like most creatures, we are "pack" animals. Look around. Most creatures prefer to be in groups. Probably some leftover instinct that keeps us safe.

We can't be alone for the simple reason that if people lived alone the race would end. Now does that mean that there aren't people who are the exception to the rule of course there are. But as a whole people need people. There have been studies done on babies in institutions who had all of their basic needs met, they were clothed, kept clean, feed on time but because they didn't have any particular person to love and to hold them they didn't develop emotionally the way that children who had one primary care giver did. In fact some of them died from lack of human contact. Who ever put us here did so together. If you believe the Bible there were always two of us and if you believe in evolution you can be pretty sure that humans didn't evolve one by one.

I disagree with what you saying, if you look at the history of human sociology it will show that love has not always existed and that humans do not need it to survive. Once the thought of marrying someone for love was laughable. We dont need to attach ourselves to other people, we can be independent on our own merits but we still need people in our lives just not really to the extent you are talking about.

From my understanding of human nature, not everyone falls into your premises. Many prefer to be alone & not because they're anti-social or hate people, just because they enjoy it. You wrote that you "understand" we need love & to be loved to achieve our highest self. If you mean this in the sense of a significant other, to whom you're "attached," this also isn't entirely true. Like many I know, & work with, I'm very comfortable with myself alone. There's a misconception that being "alone" means "lonely." Personally, I value my serenity, & I have many friends with whom I keep in touch. Unfortunately, there are people who have psychological disorders, & genuinely "dislike" people. But, that's not what you asked! Yes, it's possible, there are lots of "us." I have the feeling you're one of us!

I think your making a whole of assumptions with that question. Not everyone has a need to be with someone. Not everyone needs to be loved by someone to feel good about themselves. And, not all people who have a spouse or boyfriend or girlfriend has that person out of a need to not be alone. I think most people find a significant other to have someone enjoy life with not because we don't love ourselves.

Yes we can just love our self and be comfortable alone but some times others wise tips may help us to achieve our goals much easier and faster...So if u try to know some beautiful tips then u can do every thing urself and get success.....

More over if we only love ourself then it looks like selfishness and we should not be like that and we should love every one so that they will remember u for ever...We feel more happy when some one else loves us more than we love ourself...This is normal human's tendency...

So be good and do good and keep helping to every one and thus become good citizen.....Hope u understood what i told...

From the minute we're conceived we are not alone. We are in our mother, listening to her heartbeat, for 9 months, give or take, then we are only left alone when we are sleeping. Up until age 18, we have no option of being alone. We have school and family, or guardians.

so for our entire lives up until about 18 years we are not alone. I think that is long enough for it to be bread into us that alone is a bad thing.

because human beings were made that way. forming relationships is the way we grow. from the moment we're born to the moment we die, we have a natural instinct to reach out towards others. people always talk about our 'animal' instincts as if they were the instinct that are selfish and focused solely on self-preservation. yet humans and animals alike depend on relationships. without someone there, people go insane. one cannot love merely themselves for their entire lives and expect to think as sanely as someone who has strong relationships in their life and was able to grow. we depend on each other- even if we try to be as independent as the word means, we could never grow and become who relationships allow us too.

I like my own company. I can spend a lot of time on my own without worrying about it at all. But there comes a point when everyone needs to interact with other people. Without human interaction we become introvert, and our thought processes become obscure.

Many people live a single life happily, but most have a wide circle of friends to fulfill the human interaction that we all need.

Animals and yes it includes humans, are mostly social animals. Most mammals, many birds, and some fish and lizards are community animals. The idea is that you have a better chance of survival in a pack than alone.

Being that we descended from animals, I'd say it's a leftover trait.

We are emotional people who need others company, and comfort. It makes us feel important to help others. It's not just about being alone, but doing for others.
