There is a myth among the herd that loners are people without social skills. But this is just a copout excuse to ostracize others and try to place them below you on the pecking order. The truth is something quite different and outside the box, beyond the paradigm of the conformist.
Many loners are people who have discovered an authentic life, inner or outer, and prefer it to the fakeness and pretentiousness of "going through the motions" with others in groups and parties. When one sees life clearer and the bigger picture, it often feels better to be alone than to compromise your truth by conforming to the fakeness of others. Such loners realize that their "inner authenticity" is more precious and true than the hassle of dealing with others and the pretentiousness and lies that go along with it.
Moreover, when one is "awake" one will find that spending too much time around people who are "unawake" will compromise their "wakefulness" and drag them down. It will contract them rather than expand them, unless they are among similar folks who are also awake. Thus the awakened must spend more time alone in order to maintain the clarity of their mental/spiritual state, lest he/she be dragged down by the unawakened.
Thus, loners tend to be more authentic and sane than popular people, who have to practice being good liars in order to get along with the maximum number of people. The sad truth is that people who tell the truth all the time have fewer friends. But this is politically incorrect and unpopular to mention because it goes against our programmed belief that majority=right and authority=truth. However great thinkers and intellectuals, have transcended the need to conform. This sets them apart from the herd. These are the kind of people who make history.
There also seems to be more loners in fake cultures like the USA and Canada, more so than in more authentic cultures like in Russia, Latin America, parts of Europe, etc.
So this begs the question: Are the majority sane or insane?
Most hold the following assumptions:
1) The majority of people are right, normal, sane, friendly and sociable.
2) Misfits and people who don't follow the herd are crazy, insane and weird. They are the problem and to blame for any incompatibility with others.
However, many great thinkers and intellectuals with deep insight, from ages ago to recent times, have seen through this fallacy, and realized that the reverse was true. Here are some quotes from them:
"The object in life is not to be on the side of the majority, but to escape finding oneself in the ranks of the insane." - Marcus Aurelius, Roman Emperor
"It is no measure of health to be well adjusted to a profoundly sick society." - Jiddu Krishnamurti
"The men the American public admire most extravagantly are the most daring liars; the men they detest most violently are those who try to tell them the truth." - H. L. Mencken
"Even if you are a minority of one, the truth is the truth." - Gandhi
"Insanity in individuals is something rare - but in groups, parties, nations and epochs, it is the rule." - Frederich Nietzsche
