Ukrainian President Volodymyr Zelensky has expressed his "gratitude" for US military support. It comes after the heated exchange in the Oval Office, where President Trump and Vice-President Vance told Zelensky he was not thankful enough. Cicero referred to gratitude as "the parent of all virtues", but like all virtues, it plays a complex role in our moral life.

Ancient philosophers like the stoics and modern positive psychologists agree that recognising what we have rather than longing for what we don’t have can reduce anxiety and foster happiness. Expressing gratitude, they say, helps to build trust and deepens bonds between people, creating a sense of community and reciprocity. In difficult times, gratitude can provide perspective, allowing individuals to focus on what matters rather than being overwhelmed by hardship.

Gratitude sceptics, however, think that a perpetual state of thankfulness might not be that good for us. An over-emphasis on gratitude, they suggest, can make people passive and discourage ambition or protest in situations that demand change in our lives. The idea of a ‘thankless task’ implies that the absence of gratitude is sometimes necessary for virtue to exist. When gratitude is socially expected, it can damage relationships; it can feel transactional and forced rather than sincere, making it a tool for control and manipulation rather than authentic appreciation.

Whether expressing thanks is healthy or not depends on the circumstances, which requires discernment. So when should we be grateful?
