“The Philosophy of Tea is not mere aestheticism in the ordinary acceptance of the term, for it expresses conjointly with ethics and religion our whole point of view about man and nature. It is hygiene, for it enforces cleanliness; it is economics, for it shows comfort in simplicity rather than in the complex and costly; it is moral geometry, inasmuch as it defines our sense of proportion to the universe. It represents the true spirit of Eastern democracy by making all its votaries aristocrats in taste.
The long isolation of Japan from the rest of the world, so conducive to introspection, has been highly favourable to the development of Teaism. Our home and habits, costume and cuisine, porcelain, lacquer, painting–our very literature–all have been subject to its influence. No student of Japanese culture could ever ignore its presence. It has permeated the elegance of noble boudoirs, and entered the abode of the humble. Our peasants have learned to arrange flowers, our meanest labourer to offer his salutation to the rocks and waters. In our common parlance we speak of the man “with no tea” in him, when he is insusceptible to the serio-comic interests of the personal drama. Again we stigmatise the untamed aesthete who, regardless of the mundane tragedy, runs riot in the springtide of emancipated emotions, as one “with too much tea” in him.” (The Book of Tea by Kakuzo Okakura)
When Okakura wrote The Book of Tea in 1906, Japan had opened its doors to the western world about 30 years. In the first few decades, Japan was busy catching up with the west by adopting anything they could. Japan’s tradition such as ikebana and tea ceremony seemed so outdated and lost popularity. Okakura was posing an objection or skepticism against this trend and chose to highlight what was considered to be unique in the Japanese culture.
