Time is the most precious resource we have. It is irreversible and nonrenewable. It makes the difference, more than ever, between the best and worst scenarios of climate change, energy competition, economic development, poverty, and security. Despite this, an incredible amount of time is wasted, especially the time of others and of nature. These latter resources are needed to prevent violence, build sustainable security, and ensure the well-being of all. Therefore, it is high time to radically change the way we deal with time and to develop a more adaptive “temporament.” This article defines time, surveys temporal deficiencies, and presents the parameters of a more responsible way of dealing with time in conflict transformation.
