  • Staying Optimistic: the Trials and Tribulations of Leibnizian Optimism
    Strickland, Lloyd 2019 Staying Optimistic: The Trials and Tribulations of Leibnizian Optimism. Journal of Modern Philosophy, 1(1): 3, pp. 1–21. DOI: https://doi.org/10.32881/jomp.3 RESEARCH Staying Optimistic: The Trials and Tribulations of Leibnizian Optimism Lloyd Strickland Manchester Metropolitan University, GB [email protected] The oft-told story of Leibniz’s doctrine of the best world, or optimism, is that it enjoyed a great deal of popularity in the eighteenth century until the massive earthquake that struck Lisbon on 1 November 1755 destroyed its support. Despite its long history, this story is nothing more than a commentators’ fiction that has become accepted wisdom not through sheer weight of evidence but through sheer frequency of repetition. In this paper we shall examine the reception of Leibniz’s doctrine of the best world in the eighteenth century in order to get a clearer understanding of what its fate really was. As we shall see, while Leibniz’s doctrine did win a good number of adherents in the 1720s and 1730s, especially in Germany, support for it had largely dried up by the mid-1740s; moreover, while opponents of Leibniz’s doctrine were few and far between in the 1710s and 1720s, they became increasing vocal in the 1730s and afterwards, between them producing an array of objections that served to make Leibnizian optimism both philosophically and theologically toxic years before the Lisbon earthquake struck. Keywords: Leibniz; Optimism; Best world; Lisbon earthquake; Evil; Wolff The oft-told story of Leibniz’s doctrine of the best world, or optimism, is that it enjoyed a great deal of popularity in the eighteenth century until the massive earthquake that struck Lisbon on 1 November 1755 destroyed its support.

  • Great Chain of Being
    Great Chain of Being The great chain of being is a strict, religious hierarchical structure of all matter and life, believed to have been decreed by God. The chain starts from God and progresses downward to angels, demons (fallen/renegade angels), stars, moon, kings, princes, nobles, commoners, wild animals, domesticated animals, trees, other plants, precious stones, precious metals, and other minerals. Each link in the chain might be divided further into its component parts. The chain of being is composed of a great number of hierarchical links, from the most basic and foundational elements up through the very highest perfection, in other words, God. God sits at the top of the chain, and beneath him sit the angels, both existing wholly in spirit form. Earthly flesh is fallible and ever-changing, mutable. Spirit, however, is unchanging and permanent. This sense of permanence is crucial to understanding this conception of reality. It is generally impossible to change the position of an object in the hierarchy. (One exception might be in the realm of alchemy, where alchemists attempted to transmute base elements, such as lead, into higher elements, either silver or, more often, gold the highest element.) In the natural order, earth (rock) is at the bottom of the chain; this element possesses only the attribute of existence. Each link succeeding upward contains the positive attributes of the previous link and adds at least one other. Rocks possess only existence; the next link up is plants which possess life and existence. Animals add motion and appetite as well. Man is both mortal flesh, as those below him, and also spirit, as those above.

  • The Great Chain of Being Is Still Here Emanuele Rigato*† and Alessandro Minelli†
    Rigato and Minelli Evolution: Education and Outreach 2013, 6:18 http://www.evolution-outreach.com/content/6/1/18 RESEARCH ARTICLE Open Access The great chain of being is still here Emanuele Rigato*† and Alessandro Minelli† Abstract Background: Professional papers in evolutionary biology continue to host expressions in agreement with the pre- evolutionary metaphor of the scala naturae (the great chain of being), when contrasting ‘lower’ to ‘higher’ representatives of a given branch of the tree of life. How pervasive is the persistence of progressionist, pre- evolutionary language in contemporary papers? Results: We document here the prevalence of this unexpected linguistic survival in papers published between 2005 and 2010 by 16 top scientific journals, including generalist magazines and specialist journals in evolutionary biology. Out of a total of 67,413 papers, the unexpectedly high figure of 1,287 (1.91%) returned positive hits from our search for scala naturae language. Conclusions: A quantitative appreciation of the survival of progressionist language in scientific papers is the first step towards its eradication. This will obtain by improving skills in tree thinking as well as by more careful editorial policy. Keywords: Scala naturae, Evolutionary trends, Tree thinking, Bibliometric analysis Background biology in particular, any survival of scala naturae The scala naturae, or great chain of being (Lovejoy 1936), thinking, or of the corresponding language.

  • The Theory of the Great Chain of Being (GCB) Revisited: the Case of GCB-Level-Conditioned Animal Terms Robert Kiełtyka, University of Rzeszów
    313 The theory of the Great Chain of Being (GCB) revisited: The case of GCB-level-conditioned animal terms Robert Kiełtyka, University of Rzeszów Abstract The Great Chain of Being is known as a model of the organization and perception of the surrounding reality which is deeply rooted in the European tradition and which relies on the fact that all the material/physical and spiritual entities create a hierarchy ranked from the lowest entities/beings to those occupying the highest level of the hierarchy. The Great Chain of Being and the processes it involves play an important role in the analysis of semantic change. For example, such cognitive mechanisms as anthropomorphisation and zoomorphisation understood as ascribing human or animal features to entities from the levels below and above humans or animals, are held responsible for the mechanism of zoosemy. Zoosemy is defined in the literature of the subject as a type of animal metaphor which is universally linked to evaluative changes in meaning, especially meaning pejoration. In this paper an attempt will be made to shed some light on one of the sub-types of zoosemy interpreted as an interface between a metaphorical schema and a metonymic mapping. Keywords: zoosemy, Great Chain of Being, metaphor, metonymy 1 Introduction The theoretical bases of the concept of the Great Chain of Being were developed in Antiquity by such ancient philosophers as Plato and Aristotle (cf. Nisbet 1982: 35), and it is worth mentioning that the GCB has not merely survived into our times but – more importantly – elements of its mechanism are reflected in various evolutionary theories and, recently, also in semantic investigations of natural languages.

  • Jean-Baptiste Lamarck and the Place of Irritability in the History of Life and Death
    Chapter 2 Jean-Baptiste Lamarck and the Place of Irritability in the History of Life and Death Guido Giglioni M. de Lamarck séparait la vie d’avec la nature. La nature, à ses yeux, c’était la pierre et la cendre, le granit de la tombe, la mort! La vie n’y intervenait que comme un accident étrange et singulièrement industrieux, une lutte prolongée, avec plus ou moins de succès et d’équilibre çà et là, mais toujours fi nalement vaincue; l’immobilité froide était régnante après comme devant. Charles-Augustin Sainte-Beuve, Volupté, 1834 Et metuunt magni naturam credere mundi exitiale aliquod tempus clademque manere, cum videant tantam terrarum incumbere molem! Lucretius, De rerum natura, VI, 565–567 Abstract In the history of philosophy and science, vitalism has a bad reputation, for the very defi nition of life remains remorselessly murky. And yet life also resists all attempts at reduction carried out by the logic of mechanical reason. While on a superfi cial level, life smacks of irrational exuberance, on a deeper level, it is in the very uncomfortable company of death. In this chapter, I argue that this ambivalence is particularly evident in Jean-Baptiste Lamarck’s natural philosophy. In his chemi- cal, geological, botanical and zoological views, Lamarck advocated a theory of decaying rather than living matter. He characterized orgasm, irritability and sensi- bility – the forms which life takes on in the physical universe – as momentary inter- ruptions of nature’s ordinary course toward death and destruction. This chapter examines Lamarck’s notion of irritability, paying special attention to his concept of “intussusception.” By intussusception, Lamarck meant a universal mechanism of G.

  • The Great Chain of Being
    Historical Background Plato (427-347 BC) – Believed in 2 worlds: the real world (ideal and eternal), and an illusionary world (imperfect and perceived through the senses). Typological view of nature – individual variation as the imperfect manifestation of ethos. Aristotle (384-322 BC) – Believed that all living organisms could be arranged in a “scale of nature” or Great Chain of Being. The ladder of life consists of graduation from inanimate material through plants, through lower animals and humans to other spiritual beings. The Great Chain of Being Carolus Linnaeus (1707-1778) – Established the modern system of taxonomy in an attempt to discover order in the diversity of life “for the greater glory of God”. Groupings based on similarity . Hierarchal relationships of organisms 1 Early Ideas About Evolution . Earth formed according to laws of physics and chemistry . Older than previously thought . Life emerggyped as distinct types .

Organisms continually arise by spontaneous generation. “Nervous fluid” acts to move each species up the “great chain of being”. Organisms develop adaptations to changing environment through the use and disuse of organs. (Heavy use attracts more “nervous fluid”.) . Acquired characteristics are inherited.

  • The Philosophical Origins of Vegetarianism: Greek Philosophers and Animal World
    The Philosophical Origins of Vegetarianism Greek Philosophers and Animal World Letterio Mauro Full Professor of History of Philosophy, University of Genoa DOI: http://dx.doi.org/10.7358/rela-2017-001-maur [email protected] ABSTRACT Coeval philosophical texts provide no information about the extent to which the Ancient World practiced vegetarianism or about its concrete aspects. However, they offer a rich array of the arguments used to both justify and promote it. The present paper will focus on the four main philosophical arguments in favor of vegetarianism. These arguments were proposed and revised by various authors. The four arguments that will be studied are: the ascetic-religious one, mainly used by the Orphic tradition and then taken up by various authors, especially the Pythagoreans; the one based on the biopsychological affinity of all living beings, and coher- ently promoted by Theophrastus; the one based on the dignity and value of the animal world, widely developed especially by Plutarch; and finally the one, central to Porphyry’s treatise, that relates abstinence from meat to the need of the soul to elevate itself to the divine and be purified of any element linking it to the body. Keywords: vegetarianism, animals in antiquity, philosophical anthropology, Or- phism, Pythagoreanism, Neoplatonism, Middleplatonism, philosophical lifestyle in antiquity, sacrifices of animals, dignity and value of the animal world. 1.
