In her book "Human Voices," Penelope Fitzgerald explores the complex nature of altruism and its effects on individuals. The quote highlights the addictive quality of helping others, suggesting that the desire to assist can be overwhelming and potentially harmful. It implies that once someone is deeply engaged in offering help, stepping back or ceasing to do so can be very challenging.

Fitzgerald's analogy of helping as a dangerous drug emphasizes the fine line between compassion and self-neglect. While helping others can lead to a sense of fulfillment and purpose, it also poses risks to one's own well-being. The notion of total abstention from helping underscores the need for balance in caring for oneself while extending support to others.
