Many supporters of open borders argue that restrictions on immigration are unjust in part because they undermine equal opportunity. Borders prevent the globally least-advantaged from pursuing desirable opportunities abroad, cementing arbitrary facts about birth and citizenship. In this paper I advance an argument from equal opportunity to global freedom of movement. In addition to preventing people from pursuing desirable opportunities, borders also create a prone, segregated population that can be dominated and exploited. Restrictions on mobility do not just trap people in bad opportunity sets—they help create bad opportunities by isolating the negative externalities of production and foreign policy. Freedom of movement can play a vital role in spreading risks and burdens, incentivizing their mitigation. Using an analysis of feudalism, segregation, and the transnational economy, I illustrate the centrality of space and mobility, showing why freedom of movement is a necessary tool for preventing political and economic oppression.

There is a growing movement advocating for using closed border policies as a tool for solving the climate crisis. On this view, which I call the green border argument, fighting climate change requires drastic reductions in the global population and/or per capita greenhouse gas (GHG) emissions. However, immigration into high-income countries—particularly from low-income countries—increases per capita emissions while leaving the population untouched. Therefore, the green border theorist argues, we should limit entry into high-income countries. I explain why this is a mistake and why the political left should embrace a pro climate and pro migrant politic. First, the argument significantly overstates the impact of immigration on global GHG emissions. Second, the progressive green border argument is normatively incoherent. It advocates for closing borders and eliminating poverty and other rights violations in sending countries. However, given the relationship between emissions and income, this argument would require rejecting all poverty reduction strategies—a conclusion the progressive theorist wants to avoid. Third, the argument is counterproductive. An open border politic better promotes climate justice. A key reason is that high-income countries perceive immigration to be one of the most serious short- and medium- term costs of climate change. Whereas closure allows them to avoid this “cost,” open borders would force them to eliminate push factors, incentivizing global adaptation and mitigation strategies. Moreover, a closed border politic creates divisions between those affected, undermining cross-border solidarity and contributing to the perception that environmentalism is a white, middle-class movement.

Knowledge how to do things is a pervasive and central element of everyday life. Yet it raises many difficult questions that must be answered by philosophers and cognitive scientists aspiring to understand human cognition and agency. What is the connection between knowing how and knowing that? Is knowledge how simply a type of ability or disposition to act? Is there an irreducibly practical form of knowledge? What is the role of the intellect in intelligent action? This volume contains fifteen state of the art essays by leading figures in philosophy and linguistics that amplify and sharpen the debate between "intellectualists" and "anti-intellectualists" about mind and action, highlighting the conceptual, empirical, and linguistic issues that motivate and sustain the conflict. The essays also explore various ways in which this debate informs central areas of ethics, philosophy of action, epistemology, philosophy of language, and philosophy of mind and cognitive science. Knowing How covers a broad range of topics dealing with tacit and procedural knowledge, the psychology of skill, expertise, intelligence and intelligent action, the nature of ability, the syntax and semantics of embedded questions, the mind-body problem, phenomenal character, epistemic injustice, moral knowledge, the epistemology of logic, linguistic competence, the connection between knowledge and understanding, and the relation between theory and practice. This is the book on knowing how--an invaluable resource for philosophers, linguists, psychologists, and others concerned with knowledge, mind, and action.
