Martin, Smith, and Stein on the Definition of Atheism:
Michael Martin:
The author of one of the most extensive and detailed books on the philosophy of atheism. He states in Atheism: A Philosophical Introduction that,
- If you look up 'atheism' in the dictionary, you will probably find it defined as the belief that there is no God. Certainly many people understand atheism in this way. Yet many atheists do not, and this is not what the term means if one considers it from the point of view of its Greek roots. In Greek 'a' means 'without' or 'not' and 'theos' means 'god.' From this standpoint an atheist would simply be someone without a belief in God, not necessarily someone who believes that God does not exist. According to its Greek roots, then, atheism is a negative veiew, characterized by the absence of belief in God.
George Smith:
The author of one of the most popular books about atheism, Atheism: The Case Against God, stated in a speech:
- Atheism, properly considered, is simply the absence or lack of theistic belief. In other words, to the question, "Do you believe in God?", if you answer, "No," for whatever reason, you are an atheist. You will often hear it said that an atheist actually denies the existence of a god or gods. This is true; many atheists do but not all. This kind of overt denial of the existence of a god or gods is a sub-category of a broader kind of approach which should in a general sense be known as atheism. This gets quite complex to go into all of the reasons why some atheists would not wish to deny that any gods exist.
In his aforementioned book, Smith wrote:
- Atheism in its basic form is not a belief: it is the absence of belief. An atheist is not primarily a person who believes that god does not exist; rather, he does not believe in the existence of a god.
Gordon Stein:
A prolific writer on atheism, humanism, freethought, and philosophy, who described atheism in his An Anthology of Atheism and Rationalism:
- The average theologian (there are exceptions, of course) uses 'atheist' to mean a person who denies the existence of a God. Even an atheist would agree that some atheists (a small minority) would fit this definition. However, most atheists would stongly dispute the adequacy of this definition. Rather, they would hold that an atheist is a person without a belief in God. The distinction is small but important. Denying something means that you have knowledge of what it is that you are being asked to affirm, but that you have rejected that particular concept. To be without a belief in God merely means that the term 'god' has no importance or possibly no meaning to you. Belief in God is not a factor in your life. Surely this is quite different from denying the existence of God. Atheism is not a belief as such. It is the lack of belief.
- When we examine the components of the word 'atheism,' we can see this distinction more clearly. The word is made up of 'a-' and '-theism.' Theism, we will all agree, is a belief in a God or gods. The prefix 'a-' can mean 'not' (or 'no') or 'without.' If it means 'not,' then we have as an atheist someone who is not a theist (i.e., someone who does not have a belief in a God or gods). If it means 'without,' then an atheist is someone without theism, or without a belief in God.
