Reason Can't Replace Experience & Observation

Our minds can only learn about external objects, in the physical world, through experience and observation. Without any prior observation or experience of either the cause or the effect, the human mind cannot comprehend the relationship between the two. For example, if a person never experienced or observed fire he or she would not know the cause of fire has the effect of heat. The human mind, ignorant of observation and experience of the properties of fire, could never reason the powers and forces that connect the two events.
