(The "general population" was represented by a group of more than 200 individuals without aphantasia who had participated in the research group's previous experiments. "People with weaker imagery might only see it 60 percent of the time. Episode Part 1. In this way, the desired habitus should become entwined with the exercise of Christian virtue.,
The great theologian Thomas Aquinas saw habit as a vital component of spiritual life.
