How can we understand the phenomena of loss and mourning in the Heideggerian framework? There is no established interpretation of Heidegger that gives an elaborate account of the phenomena of loss and mourning, let alone gauges its importance for our understanding and assessment of authentic existence in Heidegger. This paper attempts to do both. First, I give a detailed exposition of Heidegger’s analysis of the phenomena of mourning and loss and show that Heidegger’s analysis of mourning in his early and (...) late work is strikingly in line with his collectivist understanding of Being-with. This demonstrates, contrary to what some of his proponents argue, that Heidegger does not follow the kind of dynamic understanding of Being-with that places the other within fine-grained spaces of possibility. Second, with reference to Heidegger’s existential philosophy, I construct a phenomenology of mourning and grief. Though Heidegger himself fails to explain the relationships in which one mourns after a close other, we can develop a unique phenomenology of mourning with reference to Heidegger, which shows that each loss is singular and can be equiprimordial with one’s own death in opening one to the possibility of an authentic existence. In this new understanding of authenticity, loss is regarded as a powerful force, akin to death, in leading one toward their self-owned existence. (shrink)

Affects are intentional structures of beliefs and desires. Many philosophers have plausibly argued that Spinoza’s theory of ideas is a kind of theory of belief. Yet this claim has rarely been taken into account when it comes to Spinoza’s theory of affects, which is actually a part of his theory of ideas. This paper shows that if this point is taken seriously when regarding Spinoza’s theory of affects we reach significant results about the fifth part of Ethics. To show this, (...) I shall strive to show that all affects depend on some sort of beliefs by analyzing Spinoza’s theory of affects in terms of his theory of ideas, and in particular an affirmation which an idea naturally involves. From this revelation, we will be able to see that Spinoza’s theory of affects presented in the third and fourth parts of Ethics is inconsistent with the fifth part of Ethics in so far as the three therapy methods he describes at the beginning of the fifth part of Ethics are considered. I will also show that arguments by which the soundness of these therapy methods is guaranteed seem actually logically invalid. Finally, I will try to revise Spinoza’s therapy methods by taking all errors and core ideas in Spinoza’s theory of affects into consideration. (shrink)
