Computationalism defined Basic Pie Crust Nouns: 1 ½ C flour 6 T cold butter 4 T cold milk Flour for rolling dough Verbs: Cut together flour & butter till it  resembles cornmeal Add liquid 1T at a time, stirring  with a fork. Stop when dough  holds together Wrap dough in plastic wrap and  chill at least one hour or freeze to  store Apple Pie Algorithm Nouns: 2 Basic Pie Crusts 2/3 cup sugar 3 T flour 1/8 t nutmeg 1/2 t cinnamon 3 lbs tart apples, peeled, cored and sliced  into 1/4” slices 1 ½ T brandy 1 t vanilla 1 large egg yolk 1 T cream Verbs: Preheat oven to 375F. Roll out 1 pie crust and place in 9” pan. Mix sugar, flour & spices. Ad apples and mix  well. Place into pie crust. Drizzle with brandy & vanilla. Roll Out 2 nd  Crust and cover pie Seal edge & cut holes to vent. Mix egg yolk & Cream & brush crust. Bake 20 minutes. Reduce heat to 350F.  Cover edges with foil & bake till golden, 30-45  mins. Serve warm, with vanilla ice cream.

Computationalism defined The mind can be represented as an  algorithm, just like pie, sorting or  washing hair Strong Computationalism What our brain does really  is   computation “Cognition is computation” Z. Pylyshyn “The mind is a meat machine”
