pleasures of sense. We talk, therefore, of the higher pleasures--the
pleasures of knowledge and learning, of wider sympathies and love, of
the contemplation of extended prosperity and concord, of hope for
international fraternity and peace, and for a life beyond the grave.
Happiness to the highly civilized will consist, therefore, of the
surplus of these pleasures over the pains of their negation.

Self-preservation is the basal law of life, and to preserve one's-self
in happiness, the completest preservation, for happiness promotes
health, and health longevity.

The first law of living nature then is to preserve life and the
enjoyment of it, and the pleasures sought, to increase the sum of
happiness will depend on the sentiments and emotions, _i.e._, on the
faculties of mind that education and experience have developed, in the
race, or in the individual.

My first thought is for myself, and my duty is to increase the sum of my
happiness. But the mental state we call happiness is relative to the
presence or absence of this state in others. Even amongst the lower
animals, misery and distress in one of the flock militate against the
happiness of the others. In a highly developed man true happiness is
impossible in the presence of pain and misery in others and _vice
versa_; happiness is contagious and flows to us from the joy of others.
If the happiness of others then is so essential to my own happiness, I
am fulfilling the first law of life and ministering to my own
preservation in health and happiness by using my best endeavours to
promote this state in others. My material comfort too depends largely on
the labour, and love, and the contribution of others in the complex
industrial system and division of labour of the higher civilisations.
