Other Minds by Peter Godfrey-Smith: book review

Other Minds: The Octopus and the Evolution of Intelligent Life (2017) is the philosophy of science by a scuba diving scientist.

It begins in 2009 on the east coast of Australia, where Peter Godfrey-Smith is interested in the interactions between humans and cephalopods: ‘an island of mental complexity in the sea of invertebrate animals.’ Then he goes right back to the very beginning – the bilaterians before the Cambrian – evolution and revolution.

He makes a connection between ‘seaborne cells’ in the mind to a discussion on the way the octopus manipulates objects. He presents not only his view on octopus intelligence, but also the work of neuroscientists. The octopus has a large nervous system and a ‘complex active body’ with ‘rich sensory capacities’ which means that they have heightened senses.

He also discusses the exploratory and curious nature of the octopus. He ponders why their camouflage skills are excellent, yet they can’t discern colours. Why is this intelligent invertebrate so intelligent? Lifespan plays a role, says Godfrey-Smith as he examines many different reasons. Its ability to squeeze through narrow openings, its ability to hide and confuse its prey, and does living in cold, deep water also play a part?

The study of this solitary ocean animal is presented in an easy, informative way, but with a sense of passion and intrigue.

Sister cities discussed: Canberra and Islamabad

Two months ago, in March 2015, Australia and Pakistan agreed to explore ways to deepen ties. The relationship between Australia and Pakistan has been strong for decades, and the two countries continue to keep dialogues open. The annual bilateral discussions were held in Australia in March to continue engagements on a wide range of matters of mutual interest. The Pakistan delegation discussed points of interest will include sports, agriculture, economic growth, trade, border protection, business, and education. The possible twinning of the cities of Canberra, the capital of Australia, and Islamabad, the capital of Pakistan, were also on the agenda (i.e. called twin towns or sister cities). Sister City relationships are twinning arrangements that build friendships as well as government, business, culture, and community linkages. Canberra currently has international Sister City relationships with Beijing in China and Nara in Japan. One example of existing...

The acacia thorn trees of Kenya

There are nearly 800 species of acacia trees in the world, and most don’t have thorns. The famous "whistling thorn tree" and the Umbrella Thorn tree of Kenya are species of acacia that do have thorns, or spines. Giraffes and other herbivores normally eat thorny acacia foliage, but leave the whistling thorn alone. Usually spines are no deterrent to giraffes. Their long tongues are adapted to strip the leaves from the branches despite the thorns. The thorny acacia like dry and hot conditions. The thorns typically occur in pairs and are 5-8 centimetres (2-3 inches) long. Spines can be straight or curved depending on the species.
