0:24.6 | So the first two arguments I want to give are against any theory on which the mind is just something physical. |
0:33.6 | And then I'll move to something specific to biologism and a bunch of things specific to functionalism. |
0:39.3 | I kind of like this argument. |

1:50.8 | or else I can't use them to assign a meaning to something. |
1:54.8 | So if all things with meaning are physical and physical things only have meaning if they're assigned, |
