Discovery can encompass the experience of discovering something for the first time or rediscovering something that has been lost, forgotten or concealed. Discoveries can be sudden and unexpected, or they can emerge from a process of deliberate and careful planning evoked by curiosity, necessity or wonder. Discoveries can be fresh and intensely meaningful in ways that may be emotional, creative, intellectual, physical and spiritual. They can also be confronting and provocative. They can lead us to new worlds and values, stimulate new ideas, and enable us to speculate about future possibilities. Discoveries and discovering can offer new understandings and renewed perceptions of ourselves and others.
