Yinrih don't separate the concepts of science and philosophy. They see science as depending on philosophy as it rests on what are ultimately axiomatic assertions, above all that the senses accurately reflect reality. For them this is even more of a leap of faith given that they can fake sensory input while in suspension to a degree that would make René Descartes shudder.
They have a single word that denotes a body of knowledge regardless of how that knowledge was obtained, by direct observation, indirect inference, introspection, or divine revelation: <rNg> /chuff, long high strong grunt, short low weak growl/, which is often translated as “lore” in English.
