For Descartes, there is no doubt that God has the power to produce all the images that we can perceive. For objects other than bodily nature, notably: colors, sounds, tastes and pain, he claims to perceive these objects better through sensory experience. We have a faculty of passive sensation; we see it in our daily lives when we recognize the blue of the sky, the warmth of the sun and the smells of the food we eat. We also inherit an active faculty of sensation, focused on active functions such as: pain in the stomach from hunger, frostbite in the extremities during long exposure to cold weather, and withering from thirst.
