I encourage caution to be entwined with the notion of knowing and certainty to be seen as subjective as taste.
It is often thought that facts are the foundation and that imagination and myths are varied and amorphous with little relationship to the substance of science. In the civilizations I have created the nature of fantasy impacts and aligns the pathways of thought giving emphasis to certain areas of the mind. In this equation the world of the known is a construct of our dreams and how we imagine gives strength to areas of perception impacting the very way the world is experienced. So knowing is as diverse as the planets and can shift as subtly as the constellations crossing the sky.
