Visions may also be metaphorical in character, but then metaphors are detailed and precise, making it MLN2238 easier to discuss visions and their implications in a rational way. On the one hand, visions depend on context conditions, such as configurations of actors and historical backgrounds, and must be assessed with respect to these contextual issues (Grin and Grunwald, 2000, p. 49). On the other hand, visions cannot be restricted to specific contexts, because their integrative power overarches different contexts and allows them to integrate.
