Speech to students at Cambridge University (4 December 1857)
Context: People talk of the sacrifice I have made in spending so much of my life in Africa. Can that be called a sacrifice which is simply paid back as a small part of a great debt owing to our God, which we can never repay? Is that a sacrifice which brings its own blest reward in healthful activity, the consciousness of doing good, peace of mind, and a bright hope of a glorious destiny hereafter? Away with the word in such a view and with such a thought! It is emphatically no sacrifice. Say rather it is a privilege. Anxiety, sickness, suffering, or danger now and then with a foregoing of the common conveniences and charities of this life, may make us pause and cause the spirit to waver and the soul to sink; but let this only be for a moment. All these are nothing when compared with the glory which shall be revealed in and for us. I never made a sacrifice.

Context: The distinction between responsible moral agents and beings with diminished or no responsibility is coherent, real, and important. It is coherent, even if in many instances it is hard to apply; it draws an empirically real line, in that we don't all fall on one side; and, most important, the distinction matters: the use we make of it plays a crucial role in the quality and meaning of our lives. [... ] We want to hold ourselves and others responsible, but we recognize that our intuitions often support the judgement that a particular individual has "diminished responsibility" because of his or her infirmities, or because of particularly dire circumstances upon upbringing or at the time of action. We also find it plausible to judge that nonhuman animals, infants, and those who are severely handicapped mentally are not responsible at all. But since we are all more or less imperfect, will there be anyone left to be responsible after we have excused all those with good excuses? [... ] We must set up some efficiently determinable threshold for legal competence, never for a moment supposing that there couldn't be intuitively persuasive "counterexamples" to whatever line we draw, but declaring in advance that such pleas will not be entertained. [... ] The effect of such an institution [... ] is to create [... ] a class of legally culpable agents whose subsequent liability to punishment maintains the credibility of the sanctions of the laws. The institution, if it is to maintain itself, must provide for the fine tuning of its arbitrary thresholds as new information (or misinformation) emerges that might undercut its credibility. One can speculate that there is an optimal setting of the competence threshold (for any particular combination of social circumstances, degree of public sophistication, and so on) that maximizes the bracing effect of the law. A higher than optimal threshold would encourage a sort of malingering on the part of the defendants, which, if recognized by the populace, would diminish their respect for the law and hence diminish its deterrent effect. And a lower than optimal threshold would yield a diminishing return of deterrence and lead to the punishment of individuals who, in the eyes of society, "really couldn't help it." The public perception of the fairness of the law is a critical factor in its effectiveness.

Context: The view that machines cannot give rise to surprises is due, I believe, to a fallacy to which philosophers and mathematicians are particularly subject. This is the assumption that as soon as a fact is presented to a mind all consequences of that fact spring into the mind simultaneously with it. It is a very useful assumption under many circumstances, but one too easily forgets that it is false. A natural consequence of doing so is that one then assumes that there is no virtue in the mere working out of consequences from data and general principles.
Mind and Matter (1958)
Context: To my view the ‘statistical theory of time’ has an even stronger bearing on the philosophy of time than the theory of relativity. The latter, however revolutionary, leaves untouched the undirectional flow of time, which it presupposes, while the statistical theory constructs it from the order of events. This means a liberation from the tyranny of old Chronos. What we in our minds construct ourselves cannot, so I feel, have dictatorial power over our mind, neither the power of bringing it to the fore nor the power of annihilating it. But some of you, I am sure, will call this mysticism. So with all due acknowledgement to the fact that physical theory is at all times relative, in that it depends on certain basic assumptions, we may, or so I believe, assert that physical theory in its present stage strongly suggests the indestructibility of Mind by Time.
