Definition just needs negation, known variables, conjunction, disjunction, substitution and quantification [Weyl, by Lavine]
|
|
Full Idea:
For mathematics, Weyl arrived (by 1917) at a satisfactory list of definition principles: negation, identification of variables, conjunction, disjunction, substitution of constants, and existential quantification over the domain.
|
|
From:
report of Hermann Weyl (works [1917]) by Shaughan Lavine - Understanding the Infinite V.3
|
|
A reaction:
Lavine summarises this as 'first-order logic with parameters'.

Perfect love is not in spite of imperfections; the imperfections must be loved as well [Kierkegaard]
|
|
Full Idea:
To love another in spite of his weaknesses and errors and imperfections is not perfect love. No, to love is to find him lovable in spite of, and together with, his weaknesses and errors and imperfections.
|
|
From:
Søren Kierkegaard (Works of Love [1847], p.158)
|
|
A reaction:
A true romantic at heart, Kierkegaard ideally posits perfect love as unconditional love, and not just of good attributes, predicates and conditions. However, the real question for both me and Kierkegaard is, is perfect love desirable or even possible?[SY]
