A Concise Introduction to Logic
Every substitution instance of a valid form is a valid argument, but it is not the
case that every substitution instance of an invalid form is an invalid argument.
The reason is that some substitution instances of invalid forms are also
substitution ...

Perhaps a bit more surprisingly, our definitions allow “Roses are red and roses
are red” to be a substitution instance of “p & q.” This example makes sense if you
compare it to variables in mathematics. Using only positive integers, how many ...

A Concise Introduction to Logic:
Bs Cs This diagram suggests that we can prove the form invalid if we can find a
substitution instance having actually true premises and an actually false
conclusion. In such a substitution instance the As and the Cs would be separated
from ...

Handbook of Modal Logic
We shall call φ[ψ/P(x)] a substitution-instance of φ. It might be instructive to
consider an example of a substitution-instance: If φ is the formula ∀y(P(y) ∧ Q(y)
) and ψ is the formula R(z,x) where z is distinct from x and y, then φ[ψ/P(x)] is the

latter case as it is in the former. And if we drop this demand on 'y is a substitution
instance of "<)>x"' as well as on 'y is true', we have to drop it on '§x too. To see the
point clearly we can take first the substitutional version of 'For all x, <}>x', ...

Introducing Symbolic Logic
The antecedent is false and the consequent true, so this substitution instance is
true. All those three substitution instances are true. What would it take for there to
be a substitution instance which is false? There would have to be an instantiating

instance of<j> is true in 971'. (iii) 7/SW Ih A then W Ih A. Proof. Item (i) follows by
