which might include genocidal events, such as the Nazi holocaust and the Rwandan massacre; wars;
large - scale natural disasters; conditions of chronic poverty, in
which millions of children die from starvation or are permanently stunted because of inadequate protein; the sexual molestation of children,

larger self of memories of our earthly passage,
which is all that, since Locke's day, the continuance of our personal identity beyond the grave has by psychology been recognized to mean.
If our finite personality here below, the objectors say, be due to the transmission through the

Physical punishment is associated with a range of mental health problems in children, youth and adults, including depression, unhappiness, anxiety, feelings of hopelessness, use of drugs and alcohol, and general psychological maladjustment.26 — 29 These relationships may be mediated by disruptions in parent — child attachment resulting from pain inflicted by a caregiver, 30,31 by increased levels of cortisol32 or by chemical disruption of the
brain's mechanism for regulating stress.33 Researchers are also finding that physical punishment is linked to slower cognitive development and adversely affects academic achievement.34 These findings come from
large longitudinal studies that control for a wide range of potential confounders.35 Intriguing results are now emerging from neuroimaging studies,
which suggest that physical punishment may reduce the volume of the
brain's grey matter in areas associated with performance on the Wechsler Adult Intelligence Scale, third edition (WAIS - III).36 In addition, physical punishment can cause alterations in the dopaminergic regions associated with vulnerability to the abuse of drugs and alcohol.37

Among the questions that this study raises are whether the surprisingly
large number of neurons in bird
brains comes at a correspondingly
large energetic cost, and whether the small neurons in bird
brains are a response to selection for small body size due to flight, or possibly the ancestral way of adding neurons to the
brain — from
which mammals, not birds, may have diverged.
