Kierkegaard and the Philosophy of Love by Michael Strawser is a beautiful book.
Strawser’s central argument is that Kierkegaard’s philosophy is not about, as Kierkegaard himself claimed, ‘How to be a Christian,’ but instead ‘How to be a lover,’ or ‘How to love.’
I approve of this assessment and I largely agree with it. Being distinctly non-Christian myself, I am sometimes asked why I describe myself as a Kierkegaardian, and Strawser’s book gives a partial answer. Kierkegaard himself had a lot of problems with organised religion, and with Christianity in particular, although he believed that there was good to be drawn from it as well.
If you’re into Kierkegaard, or you’re looking for a beautiful meditation on the philosophy of love, I’d recommend this book.
