'What is the essential essence' has been a  10 Minute Awakening Review  question asked by philosophers since the beginning of history. It is a question that has fundamental meaning but is very difficult to answer.Descartes gave one of the most famous treaties on finding true essence. In Descartes example he used wax. Here is a candle. It is made of wax that is solid and keeps its form. The candle is lit and the wax melts and runs, but is still wax. Water can be vapour, it can be liquid and it can be solid depending on temperature, but it is still water.'
