This book develops an integrative view of individuality that relies on a polysystemic approach. It considers and combines two systems, namely, individuality and intelligence with creativity in a theoretical and empirical way. It focuses on cross-theoretical and empirical integrations, unifying the theory of integral individuality of V. S. Merlin with the structural-dynamic theory of intelligence of D. V. Ushakov and the theory of divergent (creative) thinking of J. Guilford. As the book shows, these theories hold together, describing and revealing a new fragment of the integral individuality at the expense of intelligence and creativity.
