Social, emotional, and moral development in each life phase.

Sample Solution

The effects of ageing on the brain and cognition are widespread and have multiple aetiologies. Ageing has its effects on the molecules, cells, vasculature, gross morphology, and cognition. As we age our brains shrink in volume, particularly in the frontal cortex. As our vasculature ages and our blood pressure rises the possibility of stroke and ischaemia increases and our white matter develops lesions. Memory decline also occurs with ageing and brain activation becomes more bilateral for memory tasks. This may be an attempt to compensate and recruit additional networks or because specific areas are no longer easily accessed. Genetics, neurotransmitters, hormones, and experience all have a part to play in brain ageing.

g Vittola’s normative claim on authority is outdated. This is further supported by Frowe’s claim that the leader needs to represent the people’s interests, under legitimate authority, which links on to the fourth condition: Public declaration of war. Agreed with many, there must be an official announcement on a declaration of war (Frowe (2011), Page 59-60&63). Finally, the most controversial condition is that wars should have a reasonable chance of success. As Vittola reiterated, the aim of war is to establish peace and security; securing the public good. If this can’t be achieved, Frowe argues it would be better to surrender to the enemy. This can be justified because the costs of war would have been bigger (Frowe (2011), Page 56-7). Consequently, jus ad bellum comprises several conditions but most importantly: just cause and proportionality. This gives people a guide whether it’s lawful to enter a war or not. However, this is only one part of the theory of the just war. Nevertheless, it can be seen above that jus ad bellum can be debated throughout, showing that there is no definitive theory of a just war, as it is normatively theorised.

Jus in bello

The second section begins deciphering jus in bello or what actions can we classify as permissible in just wars (Begby et al (2006b), Page 323). First, it is never just to intentionally kill innocent people in wars, supported by Vittola’s first proposition. This is widely accepted as ‘all people have a right not to be killed’ and if a soldier does, they have violated that right and lost their right. This is further supported by “non-combatant immunity” (Frowe (2011), Page 151), which leads to the question of combatant qualification mentioned later in the essay. This is corroborated by the bombing of Nagasaki and Hiroshima, ending the Second World War, where millions were intently killed, just to secure the aim of war. However, sometimes civilians are accidentally killed through wars to achieve their goal of peace and security. This is supported by Vittola, who implies proportionality again to justify action: ‘care must be taken where evil doesn’t outweigh the possible benefits (Begby et al (2006b), Page 325).’ This is further supported by Frowe who explains it is lawful to unintentionally kill, whenever the combatant has full knowledge of his actions and seeks to complete his aim, but it would come at a cost.
