„The words, the style always reflects a habit of mind. And the habit of mind comes in from a different angle.“

The Architecture of Theories (1891)
Kontext: The origin of things, considered not as leading to anything, but in itself, contains the idea of First, the end of things that of Second, the process mediating between them that of Third. A philosophy which emphasises the idea of the One, is generally a dualistic philosophy in which the conception of Second receives exaggerated attention: for this One (though of course involving the idea of First) is always the other of a manifold which is not one. The idea of the Many, because variety is arbitrariness and arbitrariness is repudiation of any Secondness, has for its principal component the conception of First. In psychology Feeling is First, Sense of reaction Second, General conception Third, or mediation. In biology, the idea of arbitrary sporting is First, heredity is Second, the process whereby the accidental characters become fixed is Third. Chance is First, Law is Second, the tendency to take habits is Third. Mind is First, Matter is Second, Evolution is Third.

The Saviors of God (1923)
Kontext: Someone within me is struggling to lift a great weight, to cast off the mind and flesh by overcoming habit, laziness, necessity.
I do not know from where he comes or where he goes. I clutch at his onward march in my ephemeral breast, I listen to his panting struggle, I shudder when I touch him.

The Westminster Review, vol. 6 (1826), p. 13
Kontext: This habit of forming opinions, and acting upon them without evidence, is one of the most immoral habits of the mind.... As our opinions are the fathers of our actions, to be indifferent about the evidence of our opinions is to be indifferent about the consequences of our actions. But the consequences of our actions are the good and evil of our fellow-creatures. The habit of the neglect of evidence, therefore, is the habit of disregarding the good and evil of our fellow-creatures.
