Tissue biopsy is considered the gold standard when establishing a diagnosis of cancer. However, tissue biopsies of intraocular ophthalmic malignancies are hard to collect and are thought to be associated with a non-negligible risk of extraocular dissemination. Recently, the liquid biopsy (LB) has emerged as a viable, non-invasive, repeatable, and promising way of obtaining a diagnosis, prognosis, and theragnosis of patients with solid tumors. LB refers to blood, as well as any human liquid. The natural history of uveal melanoma (UM) and retinoblastoma (RB) are radically opposed. On the one hand, UM is known to disseminate through the bloodstream, and is, therefore, more accessible to systemic venous liquid biopsy. On the other hand, RB rarely disseminates hematogenous, and is, therefore, more accessible to local liquid biopsy by performing an anterior chamber puncture. In this review, we summarize the current knowledge concerning LB in UM, RB, conjunctival tumors, and choroidal metastases. We also develop the current limitations encountered, as well as the perspectives.

This essay argues that Ralph Waldo Emerson's interest in the cutting-edge science of his generation helps to shape his understanding of persons as fluid expressions of power rather than solid bodies. In his 1872 "Natural History of Intellect," Emerson correlates the constitution of the individual mind with the tenets of Michael Faraday's classical field theory. For Faraday, experimenting with electromagnetism reveals that the atom is a node or point on a network, and that all matter is really the arrangement of energetic lines of force. This atomic model offers Emerson a technology for envisioning a materialized subjectivity that both unravels personal identity and grants access to impersonal power. On the one hand, adopting Faraday's field theory resonates with many of the affirmative philosophical and ethical claims central to Emerson's early essays. On the other hand, however, distributing the properties of Faraday's atoms onto the properties of the person also entails moments in which materialized subjects encounter their own partiality, limitation, and suffering. I suggest that Emerson represents these aspects of experience in terms that are deliberately discrepant from his conception of universal power. He presumes that if every experience boils down to the same lines of force, then the particular can be trivialized with respect to the general. As a consequence, Emerson must insulate his philosophical assertions from contamination by our most poignant experiences of limitation. The essay concludes by distinguishing Emersonian "Necessity" from Friedrich Nietzsche's similar conception of amor fati, which routes the affirmation of fate directly through suffering.

This paper argues that the methodology Francis Bacon used in his natural histories abides by the theoretical commitments presented in his methodological writings. On the one hand, Bacon advocated a middle way between idle speculation and mere gathering of facts. On the other hand, he took a strong stance against the theorisation based on very few facts. Using two of his sources whom Bacon takes to be the reflection of these two extremes—Giambattista della Porta as an instance of idle speculations, and Hugh Platt as an instance of gathering facts without extracting knowledge—I show how Bacon chose the middle way, which consists of gathering facts and gradually extracting theory out of them. In addition, it will become clear how Bacon used the expertise of contemporary practitioners to criticise fantastical theories and purge natural history of misconceived notions and false speculations.

In this paper I explore some limits of the generalized symmetry of actor-network theory. The paper is based on a study on cows, farming technology, and farming science, and is empirically based on an anthropological fieldwork in modern, computerized cowsheds. By exploring differences in interactions between human beings and cows, on the one hand, and between human beings and computers, on the other, I argue that the partly common natural history of human beings and cows, and the lack of such a history in human–computer interactions, makes it impossible to be agnostic about where to find subjectivity in such a place as a cowshed. Animal bodies (including human beings) demand certain kinds of interactions, and thus produce certain distributions of subjectivities. The boundary of animality is not a purely ‘cultural’ distinction, and cannot be deconstructed as such.

In 1785 Kant published a series of critical reviews of Johann Gottfried Herder’s Ideas for a Philosophy of the History of Humanity (1784–1785), in which he not only challenges Herder’s conception of nature but also, and more importantly, his methodology. Kant’s complaint is that by relying on analogy, Herder draws deeply mistaken conclusions that overlook fundamental differences between human and nonhuman beings. But was Kant’s critique of Herder entirely fair? And how does it compare to Kant’s own use of analogy? My claim is that Herder’s use of analogy posed a fundamental methodological challenge to Kant, a challenge he sought to meet in the years following the reviews. In so doing, however, Kant found himself in the untenable situation of, on the one hand, granting analogy greater significance, and, on the other, severely restricting its use. By tracing the shifts in Kant’s thought through the lens of analogy, I aim to show that Kant’s transformed understanding of analogy reveals a fundamental tension between his a priori “metaphysics of nature” and empirical science, a tension that fundamentally shaped the philosophies of nature after Kant.

Cities and nature may seem mutually exclusive, but the animal inhabitants, both native and introduced, from pets to pests, are a major component of city life. Using Sydney as an example, this paper takes a critical look at cities and nature, more narrowly zoology, with a long-term view, i.e. one with intergenerational equity in mind. In the rapid conversion of bush to farmland, then suburbs and industrial areas, flora and fauna have not been given a strong voice. We need a new ethic for this new urban ecosystem, one which encompasses dealing with exotic species, pests and vermin on the one hand, and relic native animal populations on the other. Plans for sustainability in environment, economics and society need to recognise that these are interrelated subjects, not separate entities. I argue that knowing the natural history of Sydney is integral to understanding the city, its history, and its sustainability.

A dispute arising betwixt the author ( Melchior de la Ruuscher ) and a friend, concerning the substance of cochineal, the one maintaining it to be a small animal, the other the fruit, or grain of a plant, the author took the pains to procure from Antiquera in New Spain , the place where there is the greatest traffick for it, the attestations upon oath of eight persons who have been immediately employed in propagating and managing it for many years; from whence the whole natural history of this drug is collected.

In his somewhat controversial book Remnants of Auschwitz, Agamben makes brief reference to Theodor Adorno’s apparently contradictory remarks on perceptions of death post-Auschwitz, positions that Adorno had taken concerning Nazi genocidal actions that had seemed also to reflect something horribly errant in the history of thought itself. There was within such murderous acts, he had claimed, a particular degradation of death itself, a perpetration of our humanity bound in some way to affect our perception of reason itself. The contradictions regarding Auschwitz that Agamben senses to be latent within Adorno’s remarks involve the intuition ‘on the one hand, of having realized the unconditional triumph of death against life; on the other, of having degraded and debased death. Neither of these charges – perhaps like every charge, which is always a genuinely legal gesture – succeed in exhausting Auschwitz’s offense, in defining its case in point’ (RA 81). And this is the stance that Agamben wishes to hammer home quite emphatically vis-à-vis Adorno’s limitations, ones that, I would only add, seem to linger within Agamben’s own formulations in ways that he has still not come to reckon with entirely: ‘This oscillation’, he affirms, ‘betrays reason’s incapacity to identify the specific crime of Auschwitz with certainty’ (RA 81).

In integrated water management, the issues are often complex by nature, they are capable of subjective interpretation, are difficult to express in standards and exhibit many uncertainties. For such issues, an equilibrium approach is not appropriate. A non-equilibrium approach has to be applied. This implies that the processes to which the integrated issue pertains, are regarded as “alive”’. Instead of applying a control system as the model for tackling the issue, a network is used as the model. In this network, several “agents”’ are involved in the modification, revision and rearrangement of structures. It is therefore an on-going renewal process (perpetual novelty). In the planning process for the development of a groundwater policy for the municipality of Amsterdam, a non-equilibrium approach was adopted. In order to do justice to the integrated character of groundwater management, an approach was taken, containing the following features: (1) working from global to detailed, (2) taking account of the history of the system, (3) giving attention to communication, (4) building flexibility into the establishing of standards, and (5) combining reason and emotions. A middle course was sought, between static, rigid but reliable on the one hand; dynamic, flexible but vague on the other hand.

<span>The very nature of chemistry presents us with a tension. A tension between the exhilaration of diversity of substances and forms on the one hand and the safety of fundamental unity on the other. Even just the recent history of chemistry has been al1 about this tension, from the debates about Prout's hypothesis as to whether there is a primary matter in the 19th century to the more recent speculations as to whether computers will enable us to virtually dispense with experimental chemistry.</span>

The Introduction gives the background of the significance of translating and study of the text Errors of the Three Religions. The history of the development of Confucianism, Buddhism, and Daoism in Vietnam from their beginning until the eighteenth century is narrated. Particular attention is given to the different manners in which the Three Religions were taken up by nobles and literati, on the one hand, and commoners, on the other. The chapter also presents the pragmatic approach to religion taken by the Vietnamese, which was in part responsible for the receptivity of the Vietnamese to Christianity. The significance of the discovery of Errors and its impact on Vietnamese studies are also discussed.
