It is much more meaningful and enjoyable to read the scientific literature about experiments you are involved in yourself than to read about science … - Eric Kandel

Unlike vision, touch, or smell, which are prewired and based on Kantian a priori knowledge, the spatial map presents us with a new type of representation, one based on a combination of a priori knowledge and learning. The general capability for forming spatial maps is built into the mind, but the particular map is not. Unlike neurons in a sensory system, place cells are not switched on by sensory stimulation. Their collective activity represents the location where the animal thinks it is.

The Copernican revolution... revealed that the earth is not the center of the universe... The second, the Darwinian revolution... revealed that we are not created divinely or uniquely but instead evolved from simpler animals by a process of natural selection. The third great revolution, the Freudian revolution of Vienna 1900, revealed that we do not consciously control our own actions but are instead driven by unconscious motives. This... later led to the idea that human creativity... stems from conscious access to underlying, unconscious forces.

In Vienna, Modernism had three main characteristics. The first was the new view of the human mind as being largely irrational by nature. ...they questioned what constitutes reality, what lies below the surface appearances of people, objects, and events. ...They discovered that ...people harbor not only unconscious erotic feelings, but also unconscious aggressive impulses that are directed against themselves as well as against others. Freud later called these dark impulses the death instinct.
