A method for analyzing a thought system is described. One or more keywords and a degree of relation between each of the one or more keywords are obtained. An N×N matrix based on the one or more keywords and the degree of relation between each of the one or more keywords are determined. (N−1) eigenfunctions having N-dimensional components and (N−1) eigenvalues is determined from the N×N matrix using the wave equation for quantum theory. A graphical representation based on the (N−1) eigenfunctions and the (N−1) eigenvalues is generated.
