Why implication ($\phi x \Rightarrow \psi x$) is always true according to Russell? Hi @PeterSmith. If I understand T(a) = "if a is human, a is mortal" is a PF of the form $\phi x \Rightarrow \psi x$. Now what Russell says is that T(a) is always true and he is not talking about all of the PFs of the form $\phi x \Rightarrow \psi x$. Am I right? |

What does Russell mean when he defines the “Posterity… with respect to the immediate predecessor”? Am I wrong when I say that 5 belongs to {0,1,2...}?. Now, since 5 belongs to {0,1,2...} which is hereditary, then {0,1,2...} is the posterity of 5. |

What does Russell mean when he defines the “Posterity… with respect to the immediate predecessor”? Thanks @peter. I think that I understand your post, but I still missing something. When Russell says: "all those terms that belong to every hereditary class to which the given number belongs". I need an example. For example given 5. I want to identify the classes that satisfy the definition. After that, identify the members in order to form the posterity. |

Proof for the funky trace derivative : $d (\operatorname{trace} (ABA'C))$? Hi leslie. Now, I understand that proof. Your explanations was very clear. I didn't see matrix calculus and I think the matrix notation was confusing me. Thank you so much. |
