(Pleased to shared the prepared-text versions of remarks I delivered at yesterday's American Society of International Law annual meeting luncheon, at which I was introduced by my colleague, U.S. Supreme Court Justice Stephen Breyer, and further was honored with the Prominent Woman in International Law Award)
It is a real pleasure to visit with old friends like Justice Breyer – whom I wish to thank for his kind introduction – and to make new friends at this lovely event.
It is also a great honour to receive this recognition from
WILIG, the Women in International Law Interest Group of the American Society of International Law, at this annual meeting that is devoted to
“Confronting Complexity.” I draw from this honour strong support for my own writings, which reflect the non-compartmentalized – some might even say non-academic – way that I look at today’s legal world.
In my research I have continually confronted complexity.
I have looked frequently to comparative law and to international law, of course, but also to other disciplines. In mathematics, I looked to the concept of
“fuzzy logic” to help explain movements in legal pluralism. Meanwhile, looking at paintings by artists like
Maria Elena Vieira (above), and listening to music by composers like my friend
Pierre Boulez, I have found insights into the world order – and disorder.
(image credit)As one of my colleagues put it in French, “
Tu mélanges tout” – “You mix everything up.”
It’s true. I mix up different topics, and I look at them through different lenses.
Even within the law, I have looked at different topics, among them criminal law, human rights law, the law of public goods, environmental law, trade law, and labor law – also, laws relating to new technologies, such as the Internet and biomedicine.
The “different lenses” are not only the separate categories of law that interest me – national, or comparative, or even international law – but also, and more importantly, the ways that these bodies of law interact.
According to my observations, the current interaction of these bodies and topics constitutes a new phenomenon, which I call the “internationalization of law.”

The term is meant to describe a dynamic process, one that opens up legal systems and blurs the formerly entrenched borders between what is “internal” and what is “external.”
In French, the term is “
internationalisation du droit,” also known by its acronym, “
ID.” And so the
réseaux, or study networks, that I have established have been named
Réseaux ID.(above left).
If I may let you in on a secret, the term has a second meaning.
That acronym suggests this second, hidden meaning, given that “
ID” also may stand for “
imagination et droit.” In fact, the same is true in English – “internationalization of law” invites the acronym “IL,” which in turn may stand for “imagination and law.”
These thoughts provoke questions:
► How does this phenomenon of internationalization develop?
► And why is imagination necessary?
In looking for answers, I am in agreement with the theme statement for this annual meeting. My starting point, too, is “contemporary reality.” And I fully agree with the way that the statement describes that reality – as “confoundingly complex,” and “marked by rapidly evolving technologies, increasing global interconnectedness, rising population, and deepening understanding of science and the environment.”
Finally, I agree with the statement’s ultimate question. We both ask: Is law capable of responding to the challenges of complexity?
I propose 3 words that summarize – even sonorize, as if making a song – my answers. They are:
► First, ‘diversity;
► Second, perplexity”; and
► Third, “complexity.”
To grapple with diversity – as we must, in my view, because it is the best way to avoid hegemony – and to solve perplexity – necessary because of the risks of arbitrariness and disorder – we have to introduce, into law itself, complexity. And that is why we need imagination.
Let me discuss each of these concepts in turn.
