Fatalism is the view that whatever happens is unavoidable. When people say they believe in fate or destiny, they are not necessarily expressing fatalism. They may apply the concept of fate only to things that are important to them, such as love, career, and health, but not to mundane things like what to eat for breakfast. It is not clear that this selective concept of fate is even coherent.
If fatalism is true, then everything that happens is unavoidable. I find fatalism extremely hard to accept; even if there was a forceful argument for fatalism, I am not sure I would be able to accept its conclusion, that is, accept that everything that happens is unavoidable. Accepting fatalism would mean to me the loss of motivations to plan for and strive to achieve anything.
Richard Taylor thinks, however, that fatalism should imply "the attitude of calm acceptance":
And this is a comfort, both in fortune and in adversity. We shall say of him who turns out bad and mean that he was going to; of him who turns out happy and blessed that he was going to: neither praising nor berating fortune, crying over what has been, lamenting what was going to be, or passing moral judgments.
Then he goes on to ask this:
Shall we, then, sit idly by, passively observing the changing scene without participation, never testing our strength and our goodness, having no hand in what happens, or in making things come out as they should?
And his answer is:
This is a question for which each will find his own answer.
This answer can be understood fatalistically: Our attitude towards fatalism is also fated and unavoidable!
