"Yet the principle of one’s own happiness is most reprehensible, not merely because it is false and experience contradicts the pretense that one’s own welfare always accords with conducting oneself well; also not merely because it contributes nothing to the grounding of morality, since making a happy human being is something other than making a good one, and making him prudent and sharp-witted for his own advantage is something other than making him virtuous;"

Immanuel kant, The Groundwork for the Metaphysics of Morals, 4:442

On God, Humanity, and Jesus

In the mirror of this humanity of Jesus Christ the humanity of God enclosed in His deity reveals itself.  Thus God is as He is.  Thus He affirms man.  Thus He is concerned about him.  Thus He stands up for him.  The God of Schleiermacher cannot show mercy.  The God of Abraham, Isaac, and Jacob can and does.  If Jesus Christ is the Word of Truth, the 'mirror of the fatherly heart of God,' then Nietzsche's statement that man is something that must be overcome is an imprudent lie.

On Sadness And Remembrance

“My policies are based not on some economics theory, but on things I and millions like me were brought up with: an honest day’s work for an honest day’s pay; live within your means; put by a nest egg for a rainy day; pay your bills on time; support the police.”

- Margaret Thatcher (25 Oct 1925 - 8 April 2013), The News of the World, 20 September 1981.

On Opus Operatum

"This means that the church is a sign of salvation, and is not simply salvation itself. But insofar as the church is the continuation of God's self-offer in Jesus Christ in whom he has the final, victorious and salvific word in the dialogue between God and the world, the church is an efficacious sign."

On Calvin On St. Augustine On Romans 3:21

Calvin on St. Augustine on Rom 3:21 

"It is not unknown to me, that Augustine gives a different explanation; for he thinks that the righteousness of God is the grace of regeneration; and this grace he allows to be free, because God renews us, when unworthy, by his Spirit; and from this he excludes the works of the law, that is, those works, by which men of themselves endeavor, without renovation, to render God indebted to them."

 - John Calvin, Commentary on Romans

On Linguistic Puzzles

"I have a telephone conversation with New York. My friend tells me that his young trees have buds of such and such a kind. I am now convinced that his tree is... Am I also convinced that the earth exists?" 

- Ludwig Wittgenstein, On Certainty

On Freud's Methodology

"However, psychoanalysis is not just a school that flourished and faded. It is widely regarded as the paradigm of bad science, a theory so obviously false that it's proponents must be deluded or devious or both." 

- Patricia Kitcher, Freud's Dream: A Complete Interdisciplinary Science of Mind
