I must admit I haven't read it...
Are you saying that this book contains the knowledge I'd need to form such
concepts as to be able to directly comprehend (.).(.) as easily as \f g a
b -> f(g a b) ?
(since I already know how to manually convert one to the other by a
sequence of substitutions but this knowledge alone doesn't help)
If so, then I'll buy it...
Logic empowers us and Love gives us purpose.
Yet still phantoms restless for eras long past,
congealed in the present in unthought forms,
strive mightily unseen to destroy us.
