A growing cohort of philosophers argue that inference, understood as an agent-level psychological process or event, is subject to a “Taking Condition.” The Taking Condition states, roughly, that drawing an inference requires one to take one’s premise(s) to epistemically support one’s conclusion, where “takings” are some sort of higher-order attitude, thought, intuition, or act. My question is not about the nature of takings, but about their contents. I examine the prospects for “minimal” and “robust” views of the contents of takings. On the minimal view, taking one’s premise(s) to support one’s conclusion only requires focusing on propositional contents and putative epistemic support relations between them. On the robust view, taking one’s premise(s) to support one’s conclusion also requires knowledge (or being in a position to have knowledge) of the attitudes one holds toward those contents. I argue that arguments for the Taking Condition do not entail or sufficiently motivate the robust view. Accordingly, contra several philosophers, the Taking Condition does not illuminate a deep relationship between inference and self-knowledge.

In a tradition inspired by the Delphic injunction to ‘know thyself’, ancient philosophical works contain a variety of treatments of self-knowledge—of knowing the content of certain kinds of one’s own thought, or knowing one’s own status as a knower or moral agent. This book draws together contributions from an international collection of scholars working in ancient philosophy, and explores self-knowledge in ancient thought in Plato, Aristotle, Hellenistic thinkers, and Plotinus, noting continuities and discontinuities with its contemporary counterpart. The nature and structure of ancient self-knowledge is investigated in different thinkers—whether it is higher-order or a kind of self-presence, consists in a synoptic view or is diachronic, is arrived at directly via self-perception or some other kind of grasp, or mediated by dialogue or friendship with others. So too the book enquires into the relation of self-knowledge to virtue or tranquillity, either as a condition on attaining that state, or a result of the agent’s development, resulting from a process of effortful reflection.

What could a visual-led approach to the learning and teaching of complex issues look like for a short online synchronous session? Through a playful performance-lecture exploring concepts in diversity, interdisciplinarity and social change entitled What could a neurodiversity-led 2050 look like?, this paper outlines the possibilities of visual-centred approach, using the ubiquitous Microsoft software PowerPoint (or open-sourced equivalents like Google Slides and Prezi). It seeks to contribute to discourses and practices around role of visual approaches in Higher Education (HE) to address ‘difficult’ topics like power and inequality in an engaging manner, and to empower learners as active participants, including those who may be think visually, such as dyslexic learners. Such approaches will be urgent in a reality characterised by profound socio-political injustice highlighted by Black Lives Matter (BLM), and amid a global pandemic, where teaching occurs online, and where learners and teachers alike may be short of time, attention and resources. Highlighting techniques and perspectives from art, film and neurodiversity, it invites the consideration of the PowerPoint performance-lecture as a simple yet engaging and responsive process for higher order learning and creative thinking. A secondary point of the article to call for HE to itself apply a degree of critical and creative thinking about its own position, to use self-knowledge to do better, in order to move forward. It welcomes feedback and challenges, and calls for the creation of yet more playful, innovative, visual-led approaches in the learning and teaching of complex issues in Higher Education.

Abstract One family of thought about self-knowledge has argued that authoritative self-ascriptions express a form of higher-order knowledge whose special character is explained by the role that knowledge plays in rational agency. In contrast to this “regulative model”, according to Wittgenstein’s treatment of self-knowledge authoritative self-ascription of one’s present-tense mental states is explained by the fact that sincere self-ascriptions express the very states they self-ascribe. The Wittgensteinian account is epistemologically deflationary, and it makes no use of higher-order thought to account for the distinctive features of self-ascriptions. It is argued that the regulative model faces difficulties that both undermine it and reinforce the Wittgensteinian explanation. Making use of ideas from Donald Davidson and Richard Moran, an alternative first-order sketch of rational agency consistent with the expressivist view is offered.

This paper has two main goals. The first and most central goal is to develop a framework for understanding higher-order defeat. The framework rests on the idea that higher-order evidence provides direct reasons for suspending judgment which leave evidential support relations on the first order intact. Equally importantly, we also seek to explain how this sort of defeat is possible by showing how direct reasons for suspension of judgment flow from the functional profile of suspension of judgment. As a result, our framework is embedded within an account of the nature of suspension of judgment that shows how new insights about its nature lead to a different picture of its rational profile. A second and subsidiary goal of the paper is to show how our framework provides a compelling basis for more moderate positions about disagreement and epistemic akrasia. We show that the puzzles about these topics rest on more fundamental mistakes about suspension and the relationship between reasons for suspension, reasons for belief, and evidence.

The concept of inner experience in Peter John Olivi. This article discusses the notion of inner experience and self-knowledge in Peter John Olivi. According to Olivi, each act of cognition is accompanied by some sort of self-awareness or self-experience. Therefore, the problem of an infinite regress of acts of self-awareness arises. Olivi tries to solve this problem by drawing on a theory of reflection which bears a striking resemblance to modern self-representational or dispositional accounts of (self)consciousness. Thus, in order to be said to be »known« or »certain« it is not necessary for each single act of intellect to be followed by a higher-order act; Olivi argues that in many cases a simple first-order cognitive act suffices.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Among the ultra-light elements B, C, N, and O nitrogen is the most difficult element to deal with in the electron probe microanalyzer. This is mainly caused by the severe absorption that N-Kα radiation suffers in carbon which is abundantly present in the detection system (lead-stearate crystal, carbonaceous counter window). As a result the peak-to-background ratios for N-Kα measured with a conventional lead-stearate crystal can attain values well below unity in many binary nitrides . An additional complication can be caused by the presence of interfering higher-order reflections from the metal partner in the nitride specimen; notorious examples are elements such as Zr and Nb. In nitrides containing these elements is is virtually impossible to carry out an accurate background subtraction which becomes increasingly important with lower and lower peak-to-background ratios. The use of a synthetic multilayer crystal such as W/Si (2d-spacing 59.8 Å) can bring significant improvements in terms of both higher peak count rates as well as a strong suppression of higher-order reflections.

The importance of image simulation in interpreting experimental lattice images is well established. Normally, in carrying out the required theoretical calculations, only zero order Laue zone reflections are taken into account. In this paper we assess the conditions for which this procedure is valid and indicate circumstances in which higher order Laue zone reflections may be important. Our work is based on an analysis of the requirements for obtaining structure images i.e. images directly related to the projected potential. In the considerations to follow, the Bloch wave formulation of the dynamical theory has been used.The intensity in a lattice image can be obtained from the total wave function at the image plane is given by: where ϕg(z) is the diffracted beam amplitide given by In these equations,the z direction is perpendicular to the entrance surface, g is a reciprocal lattice vector, the Cg(i) are Fourier coefficients in the expression for a Bloch wave, b(i), X(i) is the Bloch wave excitation coefficient, ϒ(i)=k(i)-K, k(i) is a Bloch wave vector, K is the electron wave vector after correction for the mean inner potential of the crystal, T(q) and D(q) are the transfer function and damping function respectively, q is a scattering vector and the summation is over i=l,N where N is the number of beams taken into account.
