The proverb "Was and will make me ill I take a gramme only am" appears in Aldous Huxley's dystopian novel Brave New World. It is displayed in the Conditioning Centre where children from the lower castes are conditioned against nature. The Director explains to the students the meaning of the proverb, which is that people should not dwell on the past or the future but instead focus on the present. This is a reference to the philosophy of utilitarianism, which holds that the most important thing is to maximize happiness and minimize suffering. In the context of the novel, the proverb is a way of controlling the population and keeping them happy. By focusing on the present, people are less likely to question their society or to feel dissatisfied with their lot in life.
The proverb "Was and will make me ill I take a gramme only am" is a reminder to live in the present and not dwell on the past or the future. It is also a warning to be aware of the dangers of getting caught up in materialism and hedonism.
