Natural conditions change, cultural conditions change faster. Even so, in the past cultural conditions advanced at a pace slow enough for mankind to be able to stop and reflect upon them as if they were static. What we call the 'human condition' is in fact an abstraction of one or more slowly developing cultural conditions. Philosophy is the human condition writ large and analysed. A slow moving human condition allows organising structures such as morals and ethics to take root and develop.
Culture is an interactive product.
Science and technology have been developing at an explosively accelerating rate throughout this century. The relatively stable human condition is dissolving like morning mist as advances in genetic engineering, medical science, computing, communications technology etc. transform the meaning and conditions of life and work. Culture, like nature, is defined by its barriers. Cultural barriers are more moveable and emphemeral than natural barriers. Cultural barriers are built rather than found.
