Joseph R. Biden Jr.

Biden's actual working philosophy is post-Vatican-II Christian personalism — the tradition of Maritain, Mounier, Karol Wojtyła's "Person and Act," and the social encyclicals from John XXIII's Mater et Magistra (1961) and Pacem in Terris (1963) through Francis's Laudato Si' (2015) and Fratelli Tutti (2020). The moral primary is the irreducible dignity of the embodied person in their relations. His positions that depart from doctrinal Thomistic conservatism (pro-choice on abortion since 2019, public support for marriage equality since 2012, support for contraception and IVF) are coherent extensions of the personalist register; they are incoherent with Aquinas-conservative sexual ethics.

"My idea of self-worth was, simply put, my dad's idea: A job is about a lot more than a paycheck. It's about your dignity. It's about respect. It's about your place in your community." (Promises to Keep, prologue — the personalist register in his own voice)

A Senate-floor pragmatism: bills are produced through patient negotiation with whoever can deliver votes, principles are pursued through compromise that preserves the next negotiation, and the alternative to imperfect legislation is usually no legislation at all. The 2021 Bipartisan Infrastructure Law and the 2022 Inflation Reduction Act were the test cases.

"My dad used to say: 'Joey, a man is judged by how quickly he gets up after being knocked down.' Get up. Get up." (Promise Me, Dad, recurrent)

A working international realism shaped by decades on the Senate Foreign Relations Committee: alliances are the central asset, NATO is the central institution, the post-1945 American-led order is the central frame.

"America's alliances are our greatest asset, and leading with diplomacy means standing shoulder-to-shoulder with our allies and key partners once again." (Speech at the State Department, 4 February 2021)

The Francis-resonant register of Biden's Catholic social commitments — priority of labour over capital, the option for the poor, immigration as a justice question, climate as both ecological and moral. The liberation-theological lineage (Gutiérrez, Boff, Sobrino) flows through Francis to the contemporary American Catholic Left that Biden inhabits.

"We have to deal with this existential threat. I believe with every fibre of my being that climate change presents an existential threat to our way of life." (Address to Congress, 28 April 2021 — invoking Francis's Laudato Si' framing)

Biden is institutionally Catholic — weekly Mass attendance, public rosary, Catholic burial rites for his son Beau — and the institutional-sacramental life of the Roman Church is the framework within which the rest of his religious-philosophical commitments are formed. The doctrinal-Thomistic conservative tradition is NOT his position (see christian-personalism above for the substantive primary); the catholic-thomistic school is marked here at low weight only to register the institutional-sacramental Catholic identity.

"Faith sees best in the dark." (Promise Me, Dad, citing Søren Kierkegaard — the existential register, mediated through Catholic sacramental life)

A practised endurance — his first wife and infant daughter killed in 1972, his son Beau dead of brain cancer in 2015, the long political career punctuated by failed presidential runs (1988, 2008) — that Biden himself, in "Promise Me, Dad," treats as the inheritance from his father and the resource of his political life.

"For the loved ones who have been taken from us, all that's left of them is inside us — in our memories, in their lessons, in the love that lives on. … But one day, the memory of the loved one you lost will bring a smile to your lips before it brings a tear to your eye." (Promise Me, Dad, epilogue)
