Book Discussion – The Cambridge Handbook of the Right to Freedom of Thought

  • 11:00am-12:30pm ET
  • Online Event

Global Freedom of Expression at Columbia University is pleased to host a virtual event to discuss The Cambridge Handbook of the Right to Freedom of Thought, edited by Patrick O’Callaghan and Bethany Shiner. This event recognizes the Handbook’s groundbreaking contribution as the first publication of its kind to map and critically analyze the right to freedom of thought across national and regional legal frameworks.

The right to freedom of thought is increasingly invoked in debates on emerging technologies —such as neurotechnology and artificial intelligence— yet its scope, content, and application remain poorly understood. This Handbook offers a pioneering effort to map how the right is protected, interpreted, and applied across the globe. It examines eighteen jurisdictions and includes chapters that provide essential context, interdisciplinary perspectives, and in-depth analysis of the right in relation to specific challenges and conceptual questions.

The Handbook adopts an international law perspective, situating freedom of thought within key human rights instruments. By engaging with international jurisprudence and doctrine, it highlights the right’s conceptual development and its intersections with related rights, including autonomy, privacy, dignity, and freedom of expression.

The event will bring together the editors, selected contributors, and regional experts to discuss the findings and significance of this landmark publication.

Objective

The book discussion aims to:

  • Introduce the Handbook to a broader academic and advocacy community.
  • Facilitate discussion on the recognition and implementation of freedom of thought as a distinct human right.
  • Highlight the role of regional human rights systems — European, Inter-American, and African — in shaping its protection.

 

Panel I: Introduction to the Handbook

Editors Patrick O’Callaghan and Bethany Shiner will present the overarching goals of the volume, the methodology behind the country and regional reports, and the broader relevance of freedom of thought in contemporary legal scholarship and practice. The panel will also feature insights from Ahmed Shaheed, who will reflect on the comparative study presented in the Handbook, emphasizing its significance in addressing a major gap in scholarship on freedom of thought. The discussion will be moderated by Hawley Johnson, Associate Director at Columbia Global Freedom of Expression.

Before that, he was a researcher at the Centre for European Law and Politics (ZERP), Universität Bremen, Germany (2004-2007). Patrick’s background is in the legal protection of personality rights, as that field is conceptualised in the civilian private law tradition. This has led to an interest in theories of selfhood and questions about the role personality rights can play in safeguarding the opacity of the self. In this context, he has researched aspects of privacy law, the right to freedom of thought, the relationship between law and memory, including the right to be forgotten, the right to honour and reputation, and the historical development of personality rights. In contextualising his doctrinal research, Patrick draws on the methodologies of the field of law and humanities.

First Panel: “Introduction to the Handbook”

Q1. How should we distinguish the forum externum of the right to freedom of thought from freedom of expression? And if we do distinguish them, should courts apply the same standards when assessing interference, or do you think freedom of thought requires a stricter or different test than that used under freedom of expression?

Many civil and political rights have both a forum internum and a forum externum. So, for example, under the right to privacy, mental privacy is a different category to the privacy and confidentiality of one’s correspondence. What distinguishes the right to freedom of thought from other civil and political rights, including the right to freedom of expression, is that the forum internum takes on special significance. In fact, we might even argue that protection of the forum internum is the raison d’être of the right to freedom of thought. Understood in this way, it might be more accurate to speak in terms of a right to freedom of unmanifested thought which ought to have absolute protection. Once this unmanifested thought is manifested in our thought and/or behaviour, following Mill’s classic harm principle and the wording of international law, it no longer enjoys absolute protection in principle because it has the capacity to interfere with the rights of other people. If the manifestation of thought does warrant the protection of the law, it is subject to qualified protection only e.g. through the right to freedom of expression. We could say that this constitutes the forum externum of the right to freedom of thought although in actuality there has been no real legal guidance on what the forum externum of the right to freedom of thought is as far as it could be distinguished from expression or religious practice, for example.  So, the question of how we should distinguish between the manifestation of expression and thought is unclear but might have something to do with the characteristic of the expression (or practice). 

Q2. [Is there any judicial] decision or theory on the algorithm of thought?

Internationally, we found relatively few court decisions that deal squarely with the right to freedom of unmanifested thought. But we see scope for innovative pleadings in future cases, especially in the face of emerging socio-technical developments. These cases will have to deal with one of the central concerns of the book: at what point do thoughts warrant the attention of the law? Some of our behaviour (and thinking) may be quite straightforward, uncontroversial and even algorithmic in the sense of ‘first-order thinking’ as opposed to ‘second-order thinking’. Should this be protected by the law? Scholars in our book have put forward different and sometimes opposing proposals for tests as to when the right to freedom of thought is engaged. For example, Ligthart and van de Pol adopt the Campbell and Cosans v UK test of the European Court of Human Rights (is the thought sufficiently cogent, serious, cohesive and important to merit protection) whilst McCarthy-Jones and Walmsley challenge the idea that the right only protects the internal silent process of thinking (i.e. that the right ought to also protect ‘extended-thought’ and ‘thoughtspeech’).

Q3. Do you think that despite the UDHR, ICCPR, and the African, European, and American Charters, freedom of thought is sufficiently protected nowadays? Are these legislations enough, given the many violations of freedom of thought and expression?

The legal realists drew an important distinction between the law in the books and the law in action. Of course, it is one thing to say that the right to freedom of thought is adequately protected in international treaties, constitutions and high-level legislation. But it is quite another to say that this is so in practice. One of the most important themes of our book is exploring the distinction between the law in action and the law as written. Even in those jurisdictions where the right seems to have extensive protection in domestic law, we find evidence that more can be done to safeguard the right in practice. Some of this can be explained by the fact that the right is still underdeveloped and not well understood. One factor that may help fill the lacuna between law and practice is the emerging push to develop international, regional and domestic standards of human rights protection in the context of neurotechnology (see Istace and Van de Heyning). We hope that our books makes a positive contribution towards increasing the right’s profile in the context of neurotechnology and beyond.  

 

Second Panel

Regional Perspectives on Freedom of Thought – Inter-American System

Q1. In the short-term [Inter-American] regional context, what do you see as the most realistic structural remedy for pilot cases where the right to thought might be violated?

What the appropriate structural remedy would be depends on the context and facts pertaining to the violation. An appropriate remedy for the harm incurred by state propaganda will differ from a remedy for the harm caused by a malfunctioning, unsecure or surveilling commercial neurotechnology device. For some violations of the right to freedom of thought it is difficult to imagine what form of restitution could apply given the nature of the harm for the individuals impacted. How can the mind be returned to what it was before the violation? For the individual, depending on the violation compensation and rehabilitation may be necessary. Immediate remedies may also include criminal prosecutions, administrative reforms or some form of sanction against corporation. Of course, legislation prohibiting the offending conduct, system or pattern is necessary, but we hope that such legislation would be put in place preemptively not ex post facto. This is why a specific focus on how to protect the right to freedom of thought within the Inter-American human rights system is necessary. Lautaro Furfaro’s suggestion during the book launch discussion that the Office of the Special Rapporteur for Freedom of Expression acts as a driving force in setting standards on the right by creating a focused line of work on freedom of thought (alone or in relation to specific issues such as neurotechnologies) would be transformative. 

 

Regional Perspectives on Freedom of Thought – European System

Q1. When reviewing the jurisprudence you focused on some cases involving parents and their “parental consciousness” (choosing a name, sexual education at schools, religion, etc). I understand the approach from the Commission and the Court, mainly avoiding to refer to them. Yet, how do you believe it is possible to address freedom of thought by children? It should be focused on the parent -as with the Protocol 1?- or the child -as an agent him/herself?

Using parents as the procedural vehicle for FoT claims in the context of freedom of education under Article 2 of Protocol No. 1 is justified and important from the perspective of parental conscience. At the same time, it risks sidelining children’s own rights under Article 9 ECHR, which applies to “everyone,” including minors. Article 14 UN Convention on the Rights of the Child (CRC) reinforces this by recognising children’s FoT alongside parental guidance in line with evolving capacities. A dual approach seems preferable: parental conscience claims remain under Article 2 of Protocol No. 1, while children’s direct FoT rights should be recognised under Article 9 when they are personally affected as right holder (the challenge, of course, will be determining when and how a child could realistically claim this right). This model respects parents’ role while affirming children as independent rights-holders, bringing the ECHR closer in line with the CRC.

Q2. Looking at the current state of affairs, you refer to new technologies as a challenge to FoT. In the era of social media, do you think that states may have obligations to prevent and combat misinformation and disinformation since they can misguide people and affect their freedom of thought?

Being an absolute right limited to the forum internum, States must not interfere with our thoughts. The real challenge of misinformation and disinformation therefore lies in the conditions under which thought is formed. States clearly have a negative obligation not to engage in manipulation or practices that distort the free development of thought and personality, but whether they also carry a positive duty to combat disinformation is more delicate. Any attempt to regulate “truth” risks sliding into censorship and undermining both freedom of expression and FoT. A more balanced approach would read Article 9 alongside Article 10: the State’s role is not to dictate content, but to secure the condition (e.g. media pluralism, transparency, and education) that enable individuals to form their thoughts and personalities freely. Protecting FoT in the digital age is therefore less about suppressing particular ideas than about safeguarding the conditions in which everyone can exercise their mental autonomy.
