This volume sets out to explore the relationship between individual will (voluntas)
and the legal rule. What unfolds in the following pages is a wide-ranging itinerary,
moving between past and present, most notably ancient Rome and the contemporary
world.
The guiding question is as radical as it is enduring: in what way can voluntas (a
psychological impulse internal to the individual) come to determine the legal rule?
European private law tradition rests on the premise that legally binding acts – contract
and will, to mention only two paradigmatic cases – derive their force from
individual will. From the Roman sources arises, with exemplary force, the notion
of lex privata: the idea that private will itself may generate binding legal norms.
Such a premise immediately leads to further questions. Above all, it compels reflection
on the authenticity of that will: what if voluntas is compromised? The law of
defects (error, dolus, metus) opens the problem of whether distorted or corrupted
will can truly sustain the validity and effects of a legal rule.
The reflections gathered in this book approach the European civil law tradition as
a broad and unified phenomenon, one in which law is inseparably bound to the
historical and cultural contexts in which it takes shape.
