The first part of the paper illustrates that at the roots of chance discovery there is a process of disembodiment of mind. This process exhibits a new cognitive perspective on the mechanisms underling the emergence of ``scenarios'' productive for opportunities and risks. I will illustrate the centrality to chance discoverability of the disembodiment of mind from the point of view of the cognitive interplay between internal and external representations. I consider this interplay critical in analyzing the relation between chance discovery and dynamical interactions with the environment. I also think the disembodiment of mind can nicely account for low-level cognitive processes of chance production, bringing up the question of how could higher-level processes be comprised and how would they interact with lower-level ones. To the aim of explaining these higher-level mechanisms I provide the analysis of model-based and manipulative abduction, and of those external representations and epistemic mediators that furnish ``prostheses'' able to support the creation of what I call ``hybrid'' scenarios.
