It is typically the case that more can be said in disagreement than agreement. In the case of Martin Hägglund’s This Life, I think paying attention to those realms of disagreement is particularly helpful, because our deepest disagreements highlight the ways in which I am a Buddhist and he is not, even though there are core elements to his critique of Buddhism that I absolutely share.
As is the case in many extended disagreements, it can be helpful to start with a disagreement over terminology in order to make sure that what follows is clear. In Hägglund’s case, he frames his argument as one for a “secular” view over a “religious” one. I have said a great deal over the years about why I think the concept of “religion” generally obscures more than it clarifies, and there’s no need to repeat those general points here; in the present context, the important thing is that Hägglund falls victim to the same problems others do. In Hägglund’s telling, Martha Nussbaum can count as entirely “secular” despite her self-identification as Jewish, while Spinoza, the Stoics and the Epicureans all count as “religious” – even though many Epicureans explicitly rejected the gods. Such a framing, it seems to me, can only end up as the vast majority of other attempts to demarcate the “religious” from the “non-religious” do: in confusion.
