Responsibility is often divided into two categories: retrospective (looking back at what was done) and prospective (looking forward at what must be done). At its core, it involves the capacity for "agency"—the ability to make choices and understand their consequences.

• Reflect on your "sphere of influence." We often feel responsible only for direct actions, but responsibility also extends to the environments we help maintain or the silence we maintain in the face of harm.

• Responsibility is not distributed equally. Systems of power often place a higher burden of responsibility on marginalized groups to "fix" systemic issues they did not create, while those with more privilege may have the luxury of remaining "neutral."

This concept explores whether a group (a corporation, a nation, or a social movement) can be held responsible in a way that is distinct from the individuals within it. It asks: If a group causes harm, is everyone in that group at fault, even if they didn't personally pull the trigger?

• "Shared Agency" This occurs when individuals coordinate their actions toward a common goal. When that goal causes harm, the collective carries a moral weight that individual action alone cannot explain.

• In what ways do you benefit from collective actions you didn't personally authorize? How does that change your duty to address the outcomes of those actions?

Solidarity is more than just "helping" or "pity." It is a reciprocal commitment to a common cause, often born from shared vulnerability or a shared struggle against injustice. It requires an active alignment of interests and a willingness to bear costs for the sake of the group.

• Reflect on the difference between "charity" (a top-down approach) to "solidarity" (a side-by-side approach). Solidarity recognizes that your liberation is bound up with the liberation of others.

• True solidarity requires "decentering." This means ensuring that those most impacted by a specific oppression are the ones leading the movement, while others provide support and resources without taking over the narrative.

This is the study of how individual preferences are combined to reach a collective decision. It highlights the mathematical and logical difficulties in creating a "fair" system that truly reflects the will of the people.

• The "Aggregation Problem" Even if every individual is rational, the resulting group decision can sometimes be irrational or contradictory.

• Think of a group of friends trying to pick a movie. If everyone has a different "least favorite," you might end up with a choice that nobody actually likes. This is a micro-version of the challenges faced in democratic voting and policy-making.

While we usually think of morality as how we treat others, many philosophical traditions argue we have duties to ourselves. This includes the duty to develop our talents, maintain our health, and protect our own dignity.

• "Self-Respect as a Duty" You are a person with inherent value. Therefore, allowing yourself to be degraded or failing to care for your own well-being isn't just a personal mistake—it’s a failure to respect the "humanity" within yourself.

• How often do you compromise your own values to please others? Recognizing an obligation to yourself helps set boundaries that prevent burnout and resentment.

This occurs when people benefit from a shared resource or "public good" (like clean air, a union, or a group project) without contributing to its cost or upkeep. If too many people "free ride," the resource eventually collapses.

• "Collective Action Failure" It is often rational for an individual to skip the work if they get the reward anyway, but if everyone thinks this way, the reward disappears for everyone.

• Identify "invisible labor" In many settings, a few people do the bulk of the emotional or organizational work while others benefit. Breaking the free-rider cycle starts with acknowledging and redistributing that labor.
