Amid the shift towards neoliberalism and the privatization of resources, this book provides a radical new lens to view property and property theory. Boldly challenging the conventional theories of property law that have shaped our understanding for centuries, leading expert Paddy Ireland explores the rise and growth of new intangible property forms; the nature of ‘investment’ and of property-as-capital; and the empirical realities of modern property. Raising broader questions about ownership in society, the author ignites a powerful conversation about the increasingly unequal distribution of wealth, forcing us to confront that our current property system bears considerable responsibility for the current ‘polycrisis. This groundbreaking work will set the agenda for a new era in property theory.
