Intellectual fields operate not as conversations among equals but as gravitational systems structured by asymmetric concentrations of attention, reference, and discursive density. The distribution of citations across any mature domain reveals a steep power-law function in which a small minority of operators accumulate sufficient mass to curve the trajectory of subsequent production while thousands of contributors remain below the threshold of measurable macro-curvature. This asymmetry is not a failure of democratic ideals but a thermodynamic property of attention economies; bibliometric studies consistently report Gini coefficients between 0.70 and 0.90, indicating that the top percentile of authors routinely capture more than half of all citations. Such concentration is not noise requiring correction but structure requiring legibility. Without gradients of density there is no orientation, no means of distinguishing attractor basins from peripheral drift, no cartography of the forces that actually shape what becomes thinkable within a given disciplinary formation. The task therefore shifts from moral evaluation of inequality to topological description of its configuration: mapping how citation mass distributes across the field, how dispersion across subdomains operates as angular momentum, how recent acceleration distinguishes emergent nodes from sedimented authorities, how inscription into policy and infrastructure indicates capture by institutional gravity, and how certain concepts achieve nuclear autonomy, circulating without further attachment to their originating author. This is not a canon but a concentration field, a region of variable density whose gradient reveals where thought has historically accumulated sufficient weight to bend subsequent trajectories.
