In <i>On the Way to Theory</i>, Lawrence Grossberg introduces the major ways of thinking that provide the backstory for contemporary Western theory. Asking readers to think about thinking, Grossberg traces cultural and critical theory's foundations from the contested enlightenments to modern and postmodern conceptualizations of power, experience, language, and existence. He introduces key figures as historical characters and lays out the unique set of tools for thought that their "deep theories" offer. Through finely tuned and accessible descriptions of their concepts and logics, Grossberg highlights thinkers including Spinoza, Kant, Hegel, Marx, Nietzsche, Wittgenstein, Heidegger, Derrida, Foucault, Deleuze, and Hall, defining the possibilities of their thought. This book is essential for those interested in how theories shape our understanding of the world, influence our choices, and define our realities. It challenges us to recognize the multiplicity and complexities of ways of thinking in our quest for knowledge and understanding. By setting out a story of theoretical foundations, Grossberg invites readers to think toward the future of theory and expand conversations around theoretical scrutiny and criticism.
