The second person is often set in contrast to the first person. And there is a contrast. It does not reside in a difference of what is thought as I from what is thought as you. For that is not different. The contrast is that of monadic and dyadic predication, action and transaction. It is the contrast, not of I and You, but of I and I–You. The second person does not add a You to an I. It divides the I and makes it a relation. We consider, first, the form of predication that is common to first- and second-person thought. Then, we define the second person as a species of this form of thought. Last, we find the source and condition of this form of thought in a thought of this very form. This thought, being the source of its own form, is one of which one cannot be conscious from outside it. It is a last word, or, better, a first word.11. Compare Thomas Nagel's notion of a last word (Nagel 2001 Nagel, Thomas. 2001. The Last Word. Oxford: Oxford University Press. [Google Scholar]). Nagel's development of the notion reveals no reason why he should call what is last a word. From what he writes in the book, one would think its title to be “The Last Thought”. (Indeed, chapter 2 bears the title “Why We Can't Understand Thought from the Outside”.) However, if the last thought is I–You, then the last thought is a word; indeed, it is the word. In reaching for “The Last Word”, Nagel may express an inchoate appreciation of this.  相似文献

The protection of offspring against predators and competitors is especially important in organisms using spatially separated breeding resources, impeding the offspring’s chances to escape. One example of such isolated reproductive resources are phytotelmata (small water bodies in plant axils), exploited by the Neotropical poison frog Ranitomeya variabilis (Dendrobatidae) for both clutch and tadpole deposition. Because poison frog tadpoles are often cannibalistic, parents tend to avoid deposition with conspecifics. Previous studies have shown that this avoidance is based on chemical cues produced by conspecific tadpoles. Further, cues produced by phylogenetically less-related tadpoles (Bufonidae) were avoided for clutch but not tadpole depositions. We analyzed how the different responses to tadpole cues are triggered. We tested the reactions of parental R. variabilis to tadpole cues of species differing in two aspects: whether or not they are dendrobatids, and whether or not they reproduce in phytotelmata. We found that for clutch deposition, tadpole cues were always avoided, i.e., all tadpoles were treated by the frogs as if they pose a danger to the eggs. However, responses varied for tadpole depositions: while dendrobatid larvae living in phytotelmata were avoided, those breeding in streams were not. Non-poison frog tadpoles were ignored when associated with habitat other than phytotelmata, but they were preferred when living in phytotelmata. This suggests that both phylogeny and tadpole habitat are important triggers for the decisions made by R. variabilis. Only tadpoles using the same breeding resources are considered as relevant for the frog’s own larvae (i.e., as a potential danger or food resource), while further decisions are related to evolutionary relationship.  相似文献

Prospective memory (PM) involves remembering to do something at a specific time in the future. Here, we investigate the beginnings of this ability in young children (3-year-olds; Homo sapiens) and chimpanzees (Pan troglodytes) using an analogous task. Subjects were given a choice between two toys (children) or two food items (chimpanzees). The selected item was delivered immediately, whereas the unselected item was hidden in an opaque container. After completing an ongoing quantity discrimination task, subjects could request the hidden item by asking for it (children) or by pointing to the container and identifying the item on a symbol board (chimpanzees). Children and chimpanzees showed evidence of prospective-like memory in this task, as evidenced by successful retrieval of the item at the end of the task, sometimes spontaneously with no prompting from the experimenter. These findings contribute to our understanding of PM from an ontogenetic and comparative perspective.  相似文献

Most people in countries with the highest climate impact per capita are well aware of the climate crisis and do not deny the science. They worry about climate and have climate engaged attitudes. Still, their greenhouse-gas emissions are often high. How can we understand acting contrary to our knowledge? A simple answer is that we do not want to give up on benefits or compromise our quality of life. However, it is painful to live with discrepancies between knowledge and action. To be able to avoid taking the consequences of our knowledge, we deal with the gap by motivating to ourselves that the action is still acceptable. In this article, we use topical analysis to examine such processes of motivation by looking at the internal deliberation of 399 climate engaged people’s accounts of their reasoning when acting against their own knowledge. We found that these topical processes can be described in at least four different ways which we call rationalization, legitimization, justification and imploration. By focusing on topoi we can make visible how individual forms of reasoning interact with culturally developed values, habits and assumptions in creating enthymemes. We believe that these insights can contribute to understanding the conditions for climate transition communication.

This study reports on the preferences of people with inflammatory bowel disease (IBD) for their healthcare. Overall, 477 people with IBD responded to an open-ended survey question within a larger study. We qualitatively content-analysed these responses with open coding using NVivo. Respondents expressed a desire for (1) better communication, (2) multidisciplinary care, (3) better treatment, services and specialist care, (4) whole person care, (5) health promotion, (6) proactive healthcare, (7) fewer administrative issues and (8) improved hospital experience. Patients with IBD want patient-centred, multidisciplinary care. Healthcare professionals should facilitate patients’ access to proactive care.
