We may scatter the seeds of courtesy and kindness about us at little expense. Some of them will fall on good ground, and grow up into benevolence in the minds of others, and all of them will bear fruit of happiness in the bosom whence they spring.
Jeremy Bentham (1834). “Deontology: or, The science of morality: in which the harmony and co-incidence of duty and self-interest, virtue and felicity, prudence and benevolence, are explained and exemplified”, p.131
