Drunk is both an adjective and a noun. The Merriam-Webster online dictionary defines the former as “having the faculties impaired by alcohol”, and the latter as “one who is drunk”. Drunk is also the name of a book written by Edward Slingerland. The full title is “Drunk: How We Sipped, Danced, and Stumbled Our Way to Civilization”. It is a fascinating book and one I have just finished reading. The author, Slingerland, is Distinguished University Scholar and Professor of Philosophy at the University of British Columbia in Canada. While Slingerland is an academic, Drunk is a book that is written for a general audience.

The basic thesis underpinning Slingerland’s treatise is that alcohol has played, and continues to play, an important role in society; a role that is generally beneficial both to the individual and to society as a collective entity. A key characteristic of alcohol is that it triggers the release of endorphins whose effects include enhancing a person’s overall mood, while decreasing anxiety and stress levels. In our transformed, more relaxed state, alcohol helps us “with the communal demands of being human” (p. 106).

Central to Slingerland’s thesis is that part of the human brain called the prefrontal cortex (PFC), which “plays a role in regulating emotions in interpersonal relationships and social situations.” Alcohol, however, temporarily disarms the PFC, the locus of rational thinking and self-control, and make us more playful, creative, emotional, and trusting. As a result, consumption of alcohol facilities social bonding among people who may not otherwise be pre-disposed to bond and work cooperatively. As noted by Slingerland, alcohol “functions to bind together non-related individuals” (p. 257) Indeed it has fulfilled this role for thousands of years.

One of the many examples given by Slingerland is Göbekli Tepe, a Neolithic archaeological site (home to the world’s oldest known megaliths) in eastern Turkey where disparate and otherwise unconnected groups of hunter-gatherers periodically met for the purposes of ritualistic feasting. Brewing vats and images of festivals dating to around 10,000 BC have been discovered at Göbekli Tepe.
The ancient beer that was brewed played a central role in the feasting that took place there. According to the Archaeologist Oliver Dietrich and his colleagues “at the dawn of the Neolithic, hunter-gatherers congregating at Göbekli Tepe created social and ideological cohesion through the carving of decorated pillars, dancing, feasting—and, almost certainly, the drinking of beer made from fermented wild crops.” This pattern of feasting and consuming alcohol was replicated in many ancient pre-agricultural societies throughout the world.

Slingerland provides numerous more contemporary examples of the benefits of moderate alcohol consumption. He talks about visiting the Whiskey Room on a Google campus where coders retire with colleagues to have a wee dram and engage in creative back-and-forth of ideas. He also tells of getting together with his graduate students and faculty members, post-seminar, in a pub on the UBC campus. Much of the conversation revolved around research ideas, with the end result being the establishment of a new research center, a multi-million dollar grant, and a slew of high impact research projects.

It should be noted that in addition to the real-world examples of the benefits of moderate alcohol consumption, Slingerland does cite and discuss many laboratory-based scientific studies which provide support for his central thesis. With respect to maximizing creativity, how much alcohol is beneficial? That particular sweet spot is a blood alcohol content of 0.08, or the equivalent of two beers with an an ABV of around 5%.

Slingerland is an advocate of social drinking. Indeed, in his final chapter he warns against the dangers of drinking alone. He cites the work of Robin Dunbar, an evolutionary psychologist. In 2017, Dunbar co-authored a paper in which he explored the functional benefits of moderate alcohol consumption. In particular, he found that people who have a pub they they frequent on a regular basis “tend to be more socially engaged, feel more contented and are more likely to trust other members of their community than those who do not drink at all”. Visiting the same pub on a regular basis often results in engaging in social drinking with other regular customers, thus providing patrons with a strong social network. Summing up Dunbar’s findings, “moderate, social drinking brings people together, keeps them connected to their communities, and lubricates the exchange of information and building of networks (p. 192).

Slingerland also touches on a topic that is close to my heart as a professional academic – the value of attending an academic conference, as opposed to participating via Zoom or a similar communication platform. As he so eloquently states, “a unique intellectual benefit provided by in-person academic or professional conferences is the networking, brainstorming, and idea-honing that goes on over meals, over coffee breaks, and most of all informal venues, as the day draws to an end and the intoxicants come out” (p. 180). Indeed it was at an academic conference in New York City in 2012 that a conversation, over a beer, with a colleague from Kennesaw State University was the catalyst for my first paper on the craft beer industry; thus The Beer Professor was born. Since the COVID-19 pandemic, many scientific organizations offer hybrid conferences, whereby participants can choose to participate in-person or virtually. Sadly, those who choose the latter option miss out on the added value that in-person attendance bestows. As Slingerland observes, “even the best videoconference is a poor substitute for the visceral buzz of interpersonal chemistry, catalyzed by chemical intoxicants, that comes from in-person socializing in pubs and cafes” (p. 181).

While Slingerland’s book outlines the benefits of drinking alcohol, it is important to note that he warns against its excessive consumption. Indeed, his final chapter is devoted to the dark side of consuming alcohol, with a discussion of topics such as the negative health consequences, drunk driving, and the role of alcohol in contributing to violence against women. He also discusses the discovery of distillation, by which humans were able to produce spirits whose Alcohol By Volume levels are significantly higher than that of either beer or wine. According to Slingerland, “the many functional benefits of alcohol notwithstanding, distillation radically increases its danger to both individuals and society” (p. 237). During the Industrial Revolution in Europe, beers such as Guinness were considered a temperance drink, while high potency distilled spirits were not. As noted by Mark Schrad , writing in Foreign Policy, the growing availability of distilled spirits in early 19th century Europe meant that “once jovial communal celebrations devolved into drunken riots“, while “murder, other crimes, and arson all increased”. This became a concern for European Socialists who saw the devastating effects of spirits on the working class, while lining the pockets of profit-minded and predatory capitalists. In Germany, the Social Democratic Party called for a nationwide boycott of schnapps but not beer. Emile Vandervelde, leader of the Belgian Labour Party and President of the Second International (a collaborative network of European socialist parties) held the position that there’s “no real difference between the moderate use of fermented beer or wine and the complete abstinence from alcohol.” Spirits, not beer and wine, were the real problem.

Slingerland’s book is a lively read. It is well written and follows a logical flow. Anyone interested in the history of alcohol and its role in societies, ranging from ancient to modern, will find it a worthwhile purchase.
