I think we may be conflating two issues: how we know what exists, and how we make decisions. I readily admit that people make decisions not based on their senses (i.e. irrational decisions) all the time. The question I was addressing is how we know what exists. I don't know how you do that without appealing to your senses. They are the only mechanism I know for discerning anything outside our own heads.There is no self in that choice, it is motivated purly by a sensless love, it goes beyond material senses.
"Love’s a stranger to earth and heaven too;
In him are lunacies seventy-and-two."
The issue may be that humainty has now seen to many acts of self based love in the form of terrorism.
