Cet article vise à placer les rapports entre affectio et affectus au centre de l ’unité architectonique de l'Éthique. La définition d’affectus permet de connaître la vraie nature de l ’affection, montrant que ce concept ne peut pas signifier un état mais doit désigner une disposition, ou une variation de la puissance. Ainsi le couple affectio/affectus articule toutes les parties de l ’Éthique, en régissant non seulement la construction du problème éthique, mais aussi sa solution chez Spinoza.

Objective: Vaccines are effective in controlling and eradicating infectious diseases. However, adverse events following immunization (AEFI) can occur in susceptible individuals. The objective of this study was to analyze the Brazilian AEFI database and compare eight vaccines in order to profile risks of AEFIs related to the mandated pediatric schedule of immunization, considering the age and sex of the child, type of vaccine, and reported adverse events. Methods: We analyzed the Brazilian AEFI database integrating reports between 2005 and 2010 for children less than 10-years old immunized with eight mandated vaccines: diphtheria, pertussis, tetanus, Haemophilus influenzae type b (TETRA); diphtheria, tetanus, and pertussis (DTP); Bacillus Calmette–Guerin (BCG); oral poliovirus vaccine (OPV); measles, mumps, and rubella (MMR); oral rotavirus vaccine (ORV); hepatitis B (HB); and yellow fever (YF). We compared the children’s age regarding types of AEFI, evaluated AEFI factors associated with the chance of hospitalization of the child, and estimated the chance of notification of an AEFI as a function of the type of vaccine. In total, 47,105 AEFIs were observed for the mandated vaccines. Results: The highest AEFI rate was for the TETRA vaccine and the lowest was for the OPV vaccine, with 60.1 and 2.3 events per 100,000 inoculations, respectively. The TETRA vaccine showed the highest rate of hypotonic hyporesponsive episode, followed by convulsion and fever. The MMR and YF vaccines were associated with generalized rash. BCG was associated with enlarged lymph glands but showed the largest negative (protective) association with hyporesponsive events and seizures. Compared with children aged 5–9-years old, young children (<1 year) showed significantly higher odds of hospitalization. Conclusions: The Brazilian AEFI registry is useful to compare the magnitude and certain characteristics of adverse events associated with mandated pediatric vaccines.

A tese da mente estendida alega que ao menos alguns processos cognitivos se estendem para além do cérebro do organismo no sentido de que eles são constituídos por ações realizadas por esse organismo no ambiente ao seu redor. Um movimento mais radical seria alegar que ações sociais realizadas pelo organismo poderiam, pelo menos, constituir alguns dos seus processos cognitivos. Isso pode ser chamando de tese da mente socialmente estendida. Baseando-me na noção de affordance tal como ela foi desenvolvida na tradição da psicologia ecológica, defendo que a percepção se estende ao meio ambiente. Então, apoiado no fenômeno da atenção conjunta, estendo a noção de affordance para incorporar affordances sociais. Assim, a percepção pode, em algumas situações, ser também estendida socialmente.
