When it comes to intellectual things like the existence of a spirit dimension it is hard to make the journey of discovery with feelings which are made to deal with other people, find happiness, and make life decisions, but are not good at discovering great mysteries of the cosmos. Try discovering the real relationship between matter and energy with an emotion such as say ... empathy. These sort of issues are best forged aheady with science, analysis, reason, and deep thought. Sure we will have feelings about our opinions, but reason will rule, hopefully.
