The term “faith” has different meanings in different contexts. In some contexts, faith refers to an ongoing relationship between people where each party has certain obligations to the other and to break such obligations is therefore said to be “unfaithful”. Faith may also refer to certain types of community involvement or rituals.
In the context of this website, it is meant as a purely epistemic term. Here, it is intended to mean believing in something despite the lack of strong evidence or in the face of strong counterevidence. This is also referred to as “blind faith” to distinguish it from the other senses of the word. An example of faith despite the lack of strong evidence would be when one believes in the afterlife despite never having seen this. Faith in the face of strong counterevidence would be something such as when one believes that the world was created in seven days, despite the overwhelming evidence that this process took much longer.
