I here defend the thesis that the best life is the life that one plays as a game—specifically, a ‘Suitsian’ game that meets the definition proposed in The Grasshopper by Bernard Suits. Even more specifically, it is a nested, open, role-playing game where the life’s quality as a game partly depends on there being no more people than players. To defend this thesis I refute two powerful challenges to it, one from Thomas Hurka (2006) and another from within The (...) Grasshopper itself. In the process, I offer a new interpretation of that enigmatic and challenging book. (shrink)

In this essay we argue that there is a contradiction lurking at the heart of Bernard Suits's seminal book on the philosophy of games, The Grasshopper, which has oddly gone unnoticed for 43 years. Suits argues that games need inefficiency and defines inefficiency such that it wouldn't exist in Utopia. This trivially entails that there could be no games in Utopia, yet the whole normative point of The Grasshopper is that games would be the only worthwhileactivity in Utopia. (...) We then diagnose Suits's error and suggest some ways forward. (shrink)

The work under consideration attempts to discover a definition of game such as may serve as a foundation for a philosophical theory of games. It incorporates material from papers earlier published in Philosophy of Science, Ethics and in Osterhoudt's Philosophy of Sport. The exposition consists in the defense of a proposed definition against an array of criticisms until, after considerable exploration, a revised definition is arrived at to which no further objection is made. The author assures unity of form and (...) content by presenting the material in the manner of a philosophical dialogue and then by embellishing the dialogue with genial language and charming examples. As a result, it is clear that the search for a definition of game is meant to be a case that falls under the eventual definiendum. Although this work not only counters the Wittgensteinian proscription against definitions but does so relative to just that example by which Wittgenstein intended to show that the search for definitions is futile, the author cautions in the Preface that it was not his objective to write an "anti-anti-definitional manifesto." Yet engaging as this study is, the definition in which it culminates will neither dissuade the Wittgensteinians nor fully convince those more sympathetic with its aims, for the treatment of such topics as make-believe games and "Bernean" games seems less than conclusive, and the definition's implications may be problematical for questions such as, e.g., whether love-making is to be construed as a game and whether activities governed by Robert's rules of order qualify as games. The last chapter's metaphysical excursus on games, work, and life departs from the earlier playfulness, and the author's contention that ultimately it is games that make life worthwhile gives this study a serious character that goes beyond that customarily associated with a search for a definition. This study has value both for the specialist working in the philosophical theory of games and for the teacher seeking a text that will expose students to careful philosophical reasoning, analytical and critical skills, and the methodologies of counter-example and mental experiment, and do so in an imaginative and appealing way.--J.K.

Bernard Suits’ groundbreaking work, The Grasshopper: Games, Life, and Utopia, has profoundly shaped the philosophy of sport. Its sequel, Return of the Grasshopper: Games, Leisure, and the Good Life in the Third Millennium, released in October 2022, enriches scholarly understandings of Suits’ views on games, emphasizing the normative aspects of gameplay and its impact on people’s pursuit of the good life. In this book symposium, world-leading Suits scholars analyze the Suitsian conception of gameplay and its relevance to his (...) views on Utopia outlined in the sequel, covering a wide range of topics. Filip Kobiela explores counterfactual situations in Suits’ oeuvre. Christopher Bartel and Gwen Bradford scrutinize the ethical nature and ramifications of Suits’ claim that life is an unconscious game. R. Scott Kretchmar and John S. Russell present thoughtful critiques of Suits’ musing on Utopia. William J. Morgan’s contribution integrates contemporary work studies to illuminate Suits’ utopia. The symposium concludes with the editors, Francisco Javier Lopez Frias and Christopher Yorke, offering their perspectives on Suitsian Utopia, ethics, and metaethics. (shrink)

ABSTRACTThe Japanese translation of Bernard Suits's The Grasshopper was published in 2015. We report in this article the background of the translation, the way our project was operated, some notable difficulties we had and the impact that our translation has had so far. The description of the difficulties with translation touches upon how we interpreted the terms ‘lusory’ and ‘prelusory’. This article also includes an appendix describing the history of how the word ‘grasshopper’ has been translated into Japanese.

ABSTRACTThe article presents the story of the Polish translation of Bernard Suits’s The Grasshopper. It was prepared by Filip Kobiela, a philosopher and researcher of Suits’s legacy, and published in 2016. Some remarks concerning the difficulties of the translation and its peculiarities particularly related to the Polish ludic terminology have been added as well as an explanation of the translator’s attitude towards the translation as a type of game in Suits’s sense of the term. The article concludes with information (...) concerning the reception of the translation of Suits’s magnumopus in Poland and its possible impact on future research. (shrink)

A participatory rural appraisal inthree West African countries examined thepossibility for replacing chemical pesticidesto control locusts and grasshoppers with abiological control method based on anindigenous fungal pathogen. The fungus iscurrently being tested at different sites inthe Sahel and in the humid tropics of WestAfrica. Structured group interviews, individualdiscussions, and field visits, were used toobtain farmers' perceptions of locust andgrasshoppers as crop pests, their quantitativeestimation of crop losses, and theirwillingness to pay for locust control. Farmersas well as plant protection officers generallyperceived (...) locusts and grasshoppers as importantpests that cause significant damage. Farmerswere aware of some of the risks of the use ofchemical pesticides, but not of the potentialalternatives. The use of the fungus in anoil-formulation and standard Ultra Low Volume(ULV) equipment was demonstrated, and theresults discussed with farmers. Theirimpressions of biological control werefavorable, and they expressed an interest inusing the technology. Farmers' expressedwillingness to pay for locust control is small,but not negligible. Locusts and grasshoppersare very visible pests and thus amenable topressure from farmers to local administrators,as well as by farmers' relatives in the city onthe national government. Therefore, politicalpressure for locust control is strong, althoughnational governments spend little on it,depending mostly on foreign donors. Donors areincreasingly worried about the environmentaleffect of the large amounts of chemicalpesticides used on locust control, and arepushing for more benign alternatives. Theresults of the present survey indicate thatthere may be a potential market for abiopesticide against grasshoppers and locustson cash crops in the humid areas. The potentialmarket in the Sahel depends on a reduction ofcosts or a subsidy of its price. This subsidycould be justified by the expected reduction inenvironmental and health costs when replacingchemical pesticides. Since donors are thecurrent purchasers of chemical pesticides forthe Sahel, they would also be expected to beinvolved in the purchase of the biologicalproduct. (shrink)

‘Quid vero fit, quod poeta hanc plantam, tanquam munus locustae inprimis gratum, commemoret, nemo dixit; nee ego dicere possum’—so Jacobs in his note on the seventh line of this epigram. Among later commentators, Mackail thinks ‘can hardly mean “leek” here’ and he assumes it to be ‘groundsel’; Dain in the Budé edition is satisfied with the rather prosaic explanation that it is an ‘observation très juste … la cigale ne se nourrit que des sues des plantes’. I hope to show (...) that the diet of leeks and dewdrops from the mouth is promised by the love-sick swain of Meleager's poem for the same specific reason—to refresh the grasshopper's ‘voice’ for a new day's beguilement by song and persuasion to the sleep which will again free him from the cares of love. Although the ancients were aware of the means by which such insects produced their incessant sound, they remained faithful to the poetic tradition, which made them drink dew as a prelude to their singing, first found in Hesiod, Scut. 395, and clearly expressed in a couplet of Antipater of Thessalonica.

Job shop scheduling problem is one of the most difficult optimization problems in manufacturing industry, and flexible job shop scheduling problem is an extension of the classical JSP, which further challenges the algorithm performance. In FJSP, a machine should be selected for each process from a given set, which introduces another decision element within the job path, making FJSP be more difficult than traditional JSP. In this paper, a variant of grasshopper optimization algorithm named dynamic opposite learning assisted GOA (...) is proposed to solve FJSP. The recently proposed dynamic opposite learning strategy adopts the asymmetric search space to improve the exploitation ability of the algorithm and increase the possibility of finding the global optimum. Various popular benchmarks from CEC 2014 and FJSP are used to evaluate the performance of DOLGOA. Numerical results with comparisons of other classic algorithms show that DOLGOA gets obvious improvement for solving global optimization problems and is well-performed when solving FJSP. (shrink)

ABSTRACTIn this essay, I review Suits’ classic description of games and cite three kinds of problems—mischaracterizations, omissions, and ambiguities. I build on previous criticisms by myself and others leveled at his definition. However, in contrast to much of this previous work, I will present what I hope is an improved description. The latter part of the essay is devoted to defending this alternate characterization. I conclude by arguing that my revisionist work paradoxically both supports and undermines the merits of Suits’ (...) anti-Wittgensteinian efforts to identify the necessary and sufficient conditions for games.

Johnson and Hudecki argue that Bernard Suits fails to refute Wittgenstein’s ‘family resemblance’ view of games because Suits’s account of how games begin, how they are played, and the ends they involve, fails to match basic facts of player experience. In reply, the current paper describes three keys to interpreting The Grasshopper: (1) distinguishing the four perspectives from which Suits describes games, (2) recognizing Suits' dispositional view of rule following, and (3) understanding the geometrical metaphor Suits uses to describe (...) rules. In light of these, this paper argues that Johnson and Hudecki’s critiques are either mistaken or are actually affirmations of Suits' position. (shrink)

In The Grasshopper: Games, Life, and Utopia, Suits maintains the following two theses: game-playing is defined as ‘activity directed towards bringing about a specific state of affairs, using only means permitted by rules, where the rules prohibit more efficient in favour of less efficient means, and where such rules are accepted just because they make possible such activity’ and ‘game playing is what makes Utopia intelligible.’ Observing that these two theses cannot be jointly maintained absent paradox, this essay explores (...) the logical possibility that if is true, then must be false. More specifically, in the tradition of conceptual analysis it is argued that Suits’ definition of game-playing is too narrow inasmuch as it excludes really magnificent Utopian games of significance.

It was the middle of winter now and the Grasshopper was long dead. Skepticus and Prudence, being not quite grasshoppers had retreated into a burrow dug by Prudence and stocked by her for the winter.Unfortunately, Skepticus had taken the Grasshopper far too seriously and had not assisted Prudence in laying up for winter.

In The Grasshopper, Bernard Suits argues that the best life is the one whose essence is game-play. In fact, only through the concept of game-play can we understand how anything at all is worth doing. Yet this seems implausible: morality makes things worth doing independently of any game, and games are themselves subject to moral evaluation. So games must be logically posterior to morality. The current paper responds to these objections by developing the theory of Ludic Constructivism. Constructivist theories (...) such as Kant’s explain normativity in a way that is both objective and cognitivist but also mind-dependent. Roughly, constructivists ground normative structures in rational procedures. But rational agency is diverse: it is realized in different ways and to different degrees by different agents. Yet Kantian Constructivism requires a strong identity of rational procedures across rational agents. Ludic Constructivism avoids this challenge by rejecting this strong identity of agency, instead building a normative framework out of the ingredients of Suits’s definition of game-play. We want to play the best games we can. In order to do so we must play games with a certain structure: they must be nested multiplayer games in which everyone who is capable of self-originating activity is engaged as a fellow player rather than a plaything. Nested games – games that are constructed out of other games – go best when each game contributes to the value of each other game in the nest. Such game nests are “reciprocating value-maximization structures”. Our lives go best when we design, play, and revise the game of our Individual Life and we also embed that game within the highest-order nested game of Fate of Humankind. In this way, Ludic Constructivism delivers a normative system that expands Kant’s Kingdom of Ends, and a life that meets Aristotle’s conception of pleasure. (shrink)

Distinguished for the game-parabling expressed in The Grasshopper: Games, Life, and Utopia, Bernard Suits is revered as the author of the unorthodox claim that Utopia is intelligible and game playing is what makes Utopia intelligible. Reasonably embraced as a game in itself, the purpose of this metaphysical brainteaser is to present the reader with an enigma, with the challenge of its resolution serving as the very means by which one is to be brought into line with the logic of (...) the Grasshopper’s Utopian thesis. Appreciating the fine intricacies of this challenge, the purpose of this essay is to advance the quest for resolution via a consideration of play as a necessary element of the Grasshopper’s game playing Utopia. As foundational to the enigma, I begin with a portrayal of the Grasshopper’s tangle of riddles about play, games and the good life. Converging upon the insights of the Grasshopper and/or his disciples in respect to the nature, meaning and significance of play in its conceptual relati... (shrink)

The main aim of this article is to reconstruct and comment on Bernard Suits’ argument concerning the paradoxicality of the perfectly played game and explain how the argument might contribute to the game vs. performance distinction. The argument was mentioned by Suits in ‘Tricky Triad: Games, Play and Sport’ in the course of argumentation for the distinction between games and performances but it has not been presented in any of Suits’ works published during his lifetime. However, Suits’ fonds deposited in (...) the Special Collections and Archive of the University of Waterloo contains two texts that were nevertheless meant for publication: ‘A Perfectly Played Game’ (recently published as Appendix III to Suits’ Return of the Grasshopper) and unpublished ‘The Search for a Perfectly Fair Game’. The latter is a modified version of the former; there is an overlapping core in both texts, but there are also some essential differences between them. To provide a formula capable of embracing Suits’ ideas from both texts and remove the tension between the ideas of a perfectly played and perfectly fair game, I introduce the concept of a perfect game.

Genetic manipulation and purification techniques are facilitating research into the biology of arthropod neuropeptides. The red pigment concentrating hormone (RPCH)/ adipokinetic hormone (AKH) family are a conserved group of peptides which were first recognized for their hormonal activities. Biosynthesis of AKH in the grasshopper seems to proceed via a large protein precursor (12 kDa) in the cell body of the neuron, which implies precise coordination of synthesis and neural activity. Beginning with a 10 amino acid stretch of known precursor (...) protein sequence, an oligonucleotide primer approach is being used to clone a recombinant AKH gene. Once achieved, this will allow fundamental questions on the biochemistry and physiology of neuropeptides to be addressed. Such work in an arthropod system raises the intriguing possibility of studying neuropeptide level and synthetic activity in single, defined neurons. (shrink)

Traditionally, acts of sportsmanship have been upheld as worthy of praise. The purpose of this paper is to discern whether Bernard Suits’ Grasshopper -- in "The Grasshopper: Games, Life and Utopia" -- would share this approval. The paper begins with a conceptual analysis of good sportspersonship. From this, four action categories are identified including good sportspersonship in the forms of game desertion, changing the game, not trying, and lusory self-handicapping. A strategy for evaluation is derived from the (...) class='Hi'>Grasshopper’s theory. Game-playing is defined as action reflecting lusory attitude acknowledgement. Game-spoiling is introduced as action demonstrating lusory attitude abandonment. Three of the four actions categories are characterized as game-spoiling including good sportspersonship in the forms of game desertion, changing the game, and not trying. It is concluded that genuine good sportspersonship is characterized solely by altruistic forms of lusory self-handicapping. (shrink)

a single life-span. Philosophers, then, do not see more or know more, and they do not see less or know less. They aim to see less detail and more of the abstract. Their details, if you like, are abstractions. Walking on God’s earth as a pedestrian, as a farmer working his fields or as a passer-by, one’s picture of one’s surroundings is every bit as intelligent as that of the pilot riding the sky. The views of the field are radically (...) different, however. One sees only a specific field and in all lively detail: the exact pattern of the land, or even the exact outline of a given leaf, grasshopper, grain of sand even. Acquaintance with minute detail is not without its price: details may stand in the way of conjuring the big picture. It may be difficult to compare whichever field one happens to be in with far off fields, with respect to their size or shape or any other quality. One may wish to inquire if far off fields were already planted, harvested, or even if they exist. A pedestrian may find it hard or even impossible to do so. The pedestrian view contains fine points that the pilot’s map never would, but it does not necessarily contain more information, for it lacks the general context. After all, there are only so many items that one can observe and account for at a single glance, a single map, a single book, a single life-span. (shrink)

Via the existential questioning outlook supplied by the Grasshopper’s three visions as relevant to the fate of humankind – oblivion, delusion, and really magnificent games – this article seeks to alleviate some of the ambiguity surrounding Bernard Suits’ provocative claim that Utopian existence is fundamentally concerned with game-playing. Specifically, after proposing an interpretation of Suits’ parable designed to enrich the logical intelligibility of his Utopian thesis, I advance the suggestion that the Grasshopper’s picture of people playing really magnificent (...) games is reasonably interpreted as a clue that the philosopher’s quest to discern games worthy of a Utopian might very well be that which saves humanity from the desolate oblivion-delusion paradox erected as a consequence of the initial two visions.

The Grasshopper’s game-playing Utopia collapses because, ideal though it might seem to some, ultimately most of us want more out of life than game-play. Building on both The Grasshopper and the published sequels in which Bernard Suits attempts to vindicate his Utopia, the current paper reconstructs Suits’s Utopia in a new way. I start from deeper reflection on Suits’s example of John Striver, a Utopian citizen who wants to work but whose profound boredom occasions Utopia’s collapse. Although the (...) Grasshopper returns to Striver repeatedly and urges his interlocutors to bear him in mind, the case is underdeveloped and its implications undertheorized, both by Suits and his numerous commentators and critics. The Striver example reveals a picture of Utopian games as complex, dynamic, mutually responsive, and cooperative; such games are not only better for game-loving ‘Grasshoppers’ but make room in Utopia for work-loving ‘Ants’. This mutuality is the key to Utopia’s sustainability. The paper thus offers a new critique and reinterpretation of the central text in contemporary philosophy of sport and explicates the goods inherent in the ludic ideal. (shrink)

A system of environmental ethics recently developed by Lawrence Johnson may be used to analyze the moral implications of biological control. According to this system, entities are morally relevant when they possess well-being interests (i.e., functions or processes that can be better or worse in so far as the entity is concerned). In this formulation of ethical analysis, species and ecosystems are morally relevant because they are not simply aggregates of individuals, so their processes, properties, and well-being interests are not (...) reducible to the sum of their individual members. Following Johnson's thesis, species and ecosystems have morally relevant interests in surviving and maintaining themselves as integrated wholes with particular self-identities. This theoretical structure gives rise to a number of ethical criteria that are particularly relevant to biological control, which apply to the ecosystem (the extent to which it is large, native, unique, and integrated) and to the action being considered (the extent to which it is novel, omnipresent, monitored, reversible, and necessary). In these terms, it is evident that not all biological control efforts are ethically defensible. In general terms, natural biological control is most desirable, followed by augmentative strategies, classical approaches, and finally neoclassical biological control. Two specific cases (neoclassical biological control of rangeland grasshoppers and classical biological control of prickly pear cactus) illustrate the ethical concerns. Finally, it can be shown that formalized restrictions of biological control are necessary, given the unique properties of this technology. (shrink)
