Mathematics of Mind by Noel Sebastian explains intelligence as a combination of multiple mental and emotional abilities working together. It emphasizes that intelligence is not just logic or memory but a synergy of diverse components. True intelligence comes from balance and integration, not from excelling in one single area. I (L1+L2+L3+L4) *L3*phi With equation derivative From general equation: I = (L₁ + L₂ + L₃ + L₄) × L₃ · Φ Let Ψ = L₁ + L₂ + L₄ I = (L₁ + L₂ + L₄ + L₃) · L₃ · Φ I = (Ψ + L₃) · L₃ · Φ I = (ΨL₃ + L₃²) · Φ Also Φ = 1 + 0.3/6 (L₁L₂ + L₁L₃ + L₁L₄ + L₂L₃ + L₂L₄ + L₃L₄) dΦ/dL₃ = 0 + (L₁ + 0 + L₂ + 0 + L₄) 0.3/6 dΦ/dL₃ = (L₁ + L₂ + L₄) · 0.3/6 dΦ/dL₃ = (Ψ) 0.3/6 Let y = ΨL₃ + L₃² dy/dL₃ = Ψ + 2L₃ I = y · Φ dI = d(y · Φ) From synergistic nature of mind d(y · Φ) = dy/dL₃ (Φ) + dΦ/dL₃ (y) = Φ.dy/dL₃ + dΦ/dL₃ · y That is: dy/dL₃ (Φ) + dΦ/dL₃ (y) = (dy/dL₃)(dΦ/dL₃) Then dI/dL₃ = (dy/dL₃)(dΦ/dL₃) dI/dL₃ = (Ψ + 2L₃)(0.3/6)(Ψ) dI/dL₃ = (Ψ + 2L₃)(0.05Ψ) dI/dL₃ = 0.05Ψ² + 0.1L₃Ψ dI/dL₃ = 0.05Ψ² + 0.1L₃Ψ Second derivative d/dL₃(dI/dL₃) = d(0.05Ψ² + 0.1L₃Ψ) d²I/dL₃² = 0 + 0.1Ψ d²I/dL₃² = 0.1Ψ dI/dL₃ = ε ε = 0.05Ψ² + 0.1L₃Ψ Also d²I/dL₃² = 0.1Ψ But d²I/dL₃² = μ μ = 0.1Ψ Where L1 is pattern recognition L2 relationship understanding L3 consciousness L4 creative synthesis
