Kasaba reminds his readers of how Terence K. Hopkins did not dualistically separate the personal from the world-systemic in his pedagogy, and from the experience of his teaching about methods and movements. On the contrary, he illustrates well how for Hopkins the trees were the forest, and what made the forest worth understanding, saving, and cultivating. Kasaba shares the mentoring advice he received from Hopkins in terms of cultivating an ability to sift the crops from the weeds in anything we learn, including those offered by world-systems analysis, highlighting the need for adopting self-critical approaches to developing its concepts and analytical frameworks.
