Like humans, apes also have a strong spirit of inquiry. Their research in the fields of astronomy, mathematics, medicine and physics is noteworthy. This is why they devote so much of their time to philosophy, theology and ethics. The religious sentiments and practices of all apes can be traced back to their intense and endless quest for meaning. Apes are concerned about questions not only of origin but also of destiny.
Apes also have, like humans, a refined aesthetic sense.
They admire beauty and long to surround themselves with it. Again like humans, apes have a strong creative impulse. This is seen in their poetry, painting, dance, drama and music. To a lesser extent their creativity is also evident in the way they gather in weekly craft groups to weave baskets, spin wool, knit shawls, and cover photo albums. The sense of humour shared by all apes is another proof of their close kinship to humans.
