Another series of dichotomies in Tlingit thought are wet versus dry, heat versus cold, and hard versus soft. A wet, cold climate causes people to seek warm, dry shelter. The traditional Tlingit house, with its solid red cedar construction and blazing central fireplace, represented an ideal Tlingit conception of warmth, hardness, and dryness. Contrast the soggy forest floor that is covered with soft rotten trees and moist, squishy moss, both of which make for uncomfortable habitation. Three attributes that Tlingits value in a person are hardness, dryness, and heat. These can be perceived in many different ways, such as the hardness of strong bones or the hardness of a firm will; the heat given off by a healthy living man, or the heat of a passionate feeling; the dryness of clean skin and hair, or the sharp dry scent of cedar.
