How May the Idea and Nature of 'Despair' be Understood Philosophically? Thank you for your reply and I have not come across the ideas of Martha Nussbeim. You mention pessimism, and this may be important in juxtaposition with optimism. This may be a fine line, and involve wishing for the best but being prepared for the worst. This may be difficult to achieve, and could even result in the opposite, of preparation for the best, but fearing the worst, and how this may become manifest. Fear may in itself have such a strong self-fulfilling prophecy. Also, beyond the issues of religious ideas, there is the question of whether fear or faith are equal or, which is stronger in the development of human will and willpower?
You also mention the Stoics, and such a philosophy of self understanding and, discipline may be extremely important. In particular, there may be significant parallels between the ideas of Stoicism and cognitive behaviour therapy.
