The Argument From Scale Revisited

ABSTRACT

Several philosophers and scientists have claimed that modern cosmology forces us to think that humans are insignificant from the cosmic point of view. This argument for atheism derived from the scale of the universe became popular in the twentieth century, but its roots are long. Interestingly, it has not typically been considered as a very strong anti-theistic argument, and the size of the universe has also been used as proof for theism. This article offers a brief overview of how the argument from scale has been used in the past, and then discusses modern versions of it.     

A Multidimensional Approach to Apathy after Traumatic Brain Injury

Apathy is commonly described following traumatic brain injury (TBI) and is associated with serious consequences, notably for patients’ participation in rehabilitation, family life and later social reintegration. There is strong evidence in the literature of the multidimensional nature of apathy (behavioural, cognitive and emotional), but the processes underlying each dimension are still unclear. The purpose of this article is first, to provide a critical review of the current definitions and instruments used to measure apathy in neurological and psychiatric disorders, and second, to review the prevalence, characteristics, neuroanatomical correlates, relationships with other neurobehavioural disorders and mechanisms of apathy in the TBI population. In this context, we propose a new multidimensional framework that takes into account the various mechanisms at play in the facets of apathy, including not only cognitive factors, especially executive, but also affective factors (e.g., negative mood), motivational variables (e.g., anticipatory pleasure) and aspects related to personal identity (e.g., self-esteem). Future investigations that consider these various factors will help improve the understanding of apathy. This theoretical framework opens up relevant prospects for better clinical assessment and rehabilitation of these frequently described motivational disorders in patients with brain injury.     

The stability of a double-slab configuration of two-phase particles confined in a third phase

The stability of a double-slab configuration of two-phase particles confined in a third phase is studied as a function of shape in two and three dimensions. The condition of stability against splitting one phase in the particle into two separate identical slabs is shown to be the sum of the wetting factor and the change in the interface area relative to the shape of the two-phase particle. It is found that the double-slab configuration can be stable for a wide range of wetting factors and shapes.     

A case of prosopagnosia with some preserved covert remembrance of familiar faces

This paper presents the detailed analysis of a case of prosopagnosia in a 54-year-old male farmer following bioccipital vascular disease. In-depth clinical investigations confirmed the diagnosis of prosopagnosia and revealed the absence of any associated defect, except for a slight aspecific disturbance of the short-term memory. Further study of this case indicated that the trouble was not concerned with the class of complex visual stimuli, was not even concerned with facial expressions or unknown faces, was not a perceptual defect, but was related mainly to the operation of individualization. The memory hypothesis was thus retained and supported. Moreover, exploration of the difficulty indicated that the deficiency was limited to defective access to conscious information concerning faces and information associated with these faces (name, context, etc.), effectively stored in memory.     

On Being Exposed to Superior Others: Consequences of Self-Threatening Upward Social Comparisons

Being inferior to someone else can be hurtful. But what exactly happens when we found ourselves in such situations? We first address why and when upward comparison can be self-threatening and later review the effects of such threatening social comparison. We argue that two main kinds of disturbances can ensue: affective disturbances and attentional disturbances. Second, three ways to deal with self-threatening social comparison are reviewed: proactive regulation, defensive regulation, and regulation by avoidance. For each of these disturbances and regulation modes, we review empirical findings and later discuss the impact of upward comparison on performance. We conclude by going back to the very need behind the need for a positive evaluation.     

SPACE AND RELIGION: AN INTERWEAVING OF INFLUENCES

Since the earliest ages of humanity, the contemplation of the starry sky has invited the human being to ask: “Who am I? Where is my origin? What is my destiny?” The revolution introduced by modem astronomy has affected how humankind understands itself, and the development of aeronautical and then astronautical techniques introduced a new experiment for humanity—that of being citizen of the sky. By carrying out the dream of Icarus, has humanity realized the attempt of Prometheus? Would we take the place of the gods or God? Do religions have to fear the conquest of space? Despite modern science and the knowledge we have accumulated, space still holds its share of mystery, nurtured by its vast dimensions and startling beauty. Space continues to raise the issue of meaning.
