One might derive exceptional benefit from accepting the difference between ideas and what you experience. What you see, hear, smell, taste and hear is the 'effective' world - no one can argue that this tangible or intangible is as you say; explicitly, this is not what you experience. The world you experience is all, hopefully, of those sensory components combined with your biases, past experiences, a culture, your contextual disposition and other indelibles. From which henceforth springs an idea.
