In 1841 Ralph Waldo Emerson wrote an essay called “Self-Reliance” on the need for the individual to avoid conformity and false consistency.
― Ralph Waldo Emerson, Self Reliance
You can not trust the rules of the group, they might be enforced by powerful individuals in the group that have intentions and motivations for their own benefit. If you conform even if you know these rules are not right, you loose you own truth.
You can not conform to laws the government put in place, because they might change tomorrow based on corrupt politicians and the feeling of the times. For years, slavery was written in law and the next day, slavery was forbidden. You need to think for yourself in order to know what is right.
You need to make up your own mind. You can do this by practicing self-reliance. You need to be independent and find the truth about anything yourself.
You need to trust you own heart and mind, your instincts, ideas and feelings of right and wrong. And most importantly, you have to act on them in the world in order to be a real man or woman.
