Agnostic

A person who is sensible enough to admit that they have no fucking clue what is going on in the universe.

Contrary to both a Theist (someone who sits in Church thinking they have shit figured out) and an Atheist (someone who sits at Starbucks thinking they have shit figured out).

Someone who finds his life meaningful enough to pursue; without admitting or dismissing a God, and tolerant enough to respect either ways as a possible answer.

A person who believes that it can't be proven whether or not a deity exists. Really the best way to live since you don't have to deal with the arrogance that is both ends of the spectrum.

An agnostic is a person who believes that the existence of a greater power, such as a god, cannot be proven or disproved; therefore an agnostic wallows in the complexity of the existence of higher beings.

Agnostics on religion (Christianity, Islam, Buddhists, etc): Religious zealots are often viewed as ignorant by agnostics’ because of their blind following of a supreme being which may or may not exist. Agnostics will often question the existence of a supreme power because a lot of modern religious beliefs have no basis in modern logic; therefore blind following of popular religions is viewed as an easy out for people who chose not to think for themselves.

Agnostics on atheism: On the other end of the spectrum, unlike atheists, an agnostic uses a more scientific approach to their belief system. An agnostic knows that just because there is no physical proof of the existence of a higher being, it dose not automatically mean that one does not exist. An agnostic views an atheist on the same plane as a religious zealot; often because the belief that human beings are the pinnacle of intelligence and there are few things that we do not or have the potential to understand.

The realization of knowing that “we cannot know everything” is the backbone of the agnostic belief.

Someone who does not think there is enough evidence to prove or disprove God's existence. It's a valid viewpoint.

Some people say agnostics can't make up their mind or do their research on what to believe. I did my research on different religions and philosphical beliefs, and I made up my mind. And now I'm an agnostic. Deal with it.

Oh, and agnosticism isn't weak atheism. Atheism is believing that there is no God. You can be an agnostic athiest - one who doesn't believe in God. You can an agnostic deist - one who believes in a higher power. What you believe is different from what you know.

Litteraly meaning a lack of claim to knowlege. Generaly is refering to a lack of claim to knowelge about the possible existance of god(s).
One can be an agnostic theist. Meaning that while they personally believe in a god they are open to the idea that they could be wrong. Or an agnostic atheist who personally believes there is no god(s) but also admits they have no real way of knowing the truth.
The term agnostic is ment to be used in conjunction with the words theist or atheist but will often be used as a stand alone deffinition of ones beliefs. Agnostic's will often be split in the middle of these two phiolsophys.

Is the opposite of gnostic- meaning a claim to knowlege.

Someone who claims to have no knowledge of whether or not a god exists.
