the course of many generations the evolutionary process would ensure that human beings would become less aggressive and increasingly altruistic, leading eventually to a perfect society in which no one would cause another person pain. However, for evolution to produce the perfect individual it was necessary for present and future generations to experience the 'natural' consequences of their conduct. Only in this way would individuals have the incentives required to work on self-improvement and thus to hand an improved moral constitution to their descendants. Hence anything that interfered with the 'natural' relationship of conduct and consequence was to be resisted and this included the use of the coercive power of the state to relieve poverty, to provide public education, or to require compulsory vaccination. Although charitable giving was to be encouraged even it had to be limited by the consideration that suffering was frequently the result of individuals receiving the consequences of their actions. Hence too much individual benevolence directed to the 'undeserving poor' would break the link between conduct and consequence that Spencer considered fundamental to ensuring that humanity continued to evolve to a higher level of development. Spencer adopted a utilitarian standard of ultimate value – the greatest happiness of the greatest number – and the culmination of the evolutionary process would be the maximization of utility. In the perfect society individuals would not only derive pleasure from the exercise of altruism ('positive beneficence') but would aim to avoid inflicting pain on others ('negative beneficence'). They would also instinctively respect the rights of others, leading to the universal observance of the principle of justice – each person had the right to a maximum amount of liberty that was compatible with a like liberty in others. 'Liberty' was interpreted to mean the absence of coercion, and was closely connected to the right to private property. Spencer termed this code of conduct 'Absolute Ethics' which provided a scientifically-grounded moral system that could substitute for the supernaturally-based ethical systems of the past. However, he recognized that our inherited moral constitution does not currently permit us to behave in full compliance with the code of Absolute Ethics, and for this reason we need a code of 'Relative Ethics' which takes into account the distorting factors of our present imperfections. Spencer's distinctive view of musicology was also related to his ethics. Spencer thought that the origin of music is to be found in
