How do we form concepts like those of three, bycicle and red? According to Kant, we form them by carrying out acts of comparison, reflection and abstraction on information provided by the senses. Kant's answer raised numerous objections from philosophers and psychologists alike. Kant e la formazione dei concetti argues that Kant is able to rebut those objections. The book shows that, for Kant, it is possible to perceive objects without employing concepts; it explains how, given those perceptions, we can form categories and empirical concepts; and it argues that theories like Kant's – abstractionist theories of concept formation – are more plausible than is often assumed.
