Cognitive Science Sandwiches

From the menu from the Cognitive Science Café:

The Aristotelian Concept
Cucumber, tomato, balsamic vinegar, feta, and pita are individually necessary and jointly sufficient for this Greek classic.

The California Connectionist
Munster, sprouts, and mustard on whole wheat with a hidden layer of avocado.

The Perceptron
Like the California Connectionist, but without the hidden layer.

The Quine Panini
This grilled fresh mozzarella, tomato, and basil panini eliminates the distinction between sandwich and pizza.

The Prototype
Peanut butter and jelly on white bread.

The Turing Tester
Half Brie with apricot jam on a French roll, half vegan alternative — we bet you won’t know which is which!
