Kant's Groundwork of the Metaphysics of Morals: The Concept of the Goodwill and Practical Reason
Course Introduction and Administrative Procedures
Sign-in Procedures: Students are instructed to access the sign-in sheet link provided in the chat. Every student must find their name and record the current date next to it.
Transitions in Curriculum: For the past two weeks, the course focused on Aristotle's Nicomachean Ethics. The lecture now transitions to Immanuel Kant's Groundwork of the Metaphysics of Morals.
Comparative Context: While Aristotle and Kant are separated by over two thousand years, they address similar philosophical questions but apply vastly different methodologies.
The Philosophical Concept of the Will
Opening Comparisons:
Aristotle begins the Nicomachean Ethics by stating: "Every art and every inquiry and similar reaction and pursuit is taught to aim at some good." His focus is on the concept of the good.
Kant's Groundwork also starts with the good but immediately introduces the "will": "There is nothing it is possible to think of anywhere in the world or indeed anything at all outside it that can be held to be good without limitation, only a goodwill."
Historical Development: The concept of the "will" as a distinct philosophical category did not exist in Ancient Greek philosophy (including Aristotle's work). It developed much later, specifically during the Medieval period.
Defining the Will (General Philosophical Conception):
External Side: The will is the capacity to bring about changes in the external world through actions. Not all changes are acts of will (e.g., sitting and shifting molecules or being pushed and breaking a glass are not acts of will because they lack desire/intention).
Internal Side: Acts of will originate from within—from desires, thoughts, wants, or intentions. They are changes that originate in the subject rather than merely happening to them.
Student Perspectives on the Will:
One student defined the will as "what you mean to do" or your "intentions," regardless of actual outcomes in the world.
Another student described it as the "capacity for someone to choose or desire and act upon their own actions."
David Hume's Influence and his Theory of the Will
Relationship of Faculties: Kant developed his view partly in response to David Hume, specifically regarding the relationship between reason, passions, and the will.
Hume's Two Functions of Reason:
1. Relations Between Abstract Ideas: Mathematics is the primary example. For instance, the statement describes the relation between abstract entities (numbers), not physical objects.
2. Relations Between Objects: This involves discovering how physical objects relate (e.g., "fire can boil water"). This knowledge is purely empirical and known through repeated experience/observation.
Hume’s Influence on Action:
Hume argues that neither function of reason has any influence on the will by itself.
Abstract truths () do not motivate action.
Empirical knowledge (e.g., a farmer knowing that adding iron to soil helps oats grow) only influences the will if there is a pre-existing goal or desire (e.g., wanting the oats to grow faster).
Conclusion on Reason: For Hume, reason identifies the means for achieving ends that are already held. Reason never sets the ends itself. Reason is "theoretical" rather than "practical."
The Master of Reason: Hume famously stated: "Reason is and ought only to be the slave of the passions." Passions and emotions provide the goals and motivation to act.
Contrast with Aristotle: Aristotle believed in "practical rationality"—the capacity to recognize the good and strive for it. Hume rejects this, denying that reason can recognize or set a "good" end.
Kant’s Conception of the Will as Practical Reason
Identification of Terms: For Kant, the human will and "practical reason" are one and the same.
Theoretical vs. Practical Reason:
Theoretical Reason: Connects us to the world by understanding it (reasons for beliefs).
Practical Reason: Connects us to the world by changing it (reasons for actions). It recognizes what is good, and that recognition provides the reason to act.
The Rationality of Human Action:
Animals act according to instinct (e.g., drinking when thirsty).
Humans act on reasons. When a human drinks, they do so because they judge that satisfying thirst is a "good thing to do."
Because humans act in the light of judgment, we can choose not to act on a desire (e.g., a patient not drinking water before surgery because a doctor advised against it, or a person giving their water to a thirsty child because drinking it themselves would not be judged as good in that context).
Two-Fold Nature of the Will according to Kant:
1. Causal: It brings about changes in the world.
2. Rational: Those changes are guided by reasons tied to what the subject takes to be good.
The Nature of Goods with Limitation
Good without Limitation: Only a "goodwill" fits this description. Other things commonly considered "good" are actually "good with limitation" (conditional goods).
Three Types of Limitation:
1. Circumstantial Goods: Things that are good only in specific situations. Example: Pizza is good when hungry but not when full; peanuts are good for some but dangerous for those with allergies.
2. Instrumental Goods (Means to an End): Money is only good because it can be exchanged for other goods. If it lost its exchange value, it would no longer be good.
3. Qualified Goods (Subject to intent): Values like intelligence, courage, and power are good only if used for good purposes. Intelligence can be used to deceive; power can be used to harm. Without a goodwill to guide them, they can become "extremely evil and harmful."
The Comparison of the Goodwill to Virtue and Happiness
Common Rational Moral Cognition: Kant begins from everyday moral thinking rather than technical philosophical definitions.
Virtue: Kant refers to virtues like courage, resoluteness, and self-control (persistence).
In the common view, these are traits of temperament.
However, self-control in a cold-blooded murderer makes them more effective and thus more evil. Therefore, virtue is not good without limitation; its goodness is conditional upon the presence of a goodwill.
Happiness: In this context, Kant uses the common definition of happiness (getting what one wants/satisfaction of desires) rather than Aristotle’s (reason-involving activity).
Happiness can lead to "audacity," recklessness, and arrogance if not corrected by a goodwill.
Worthiness of Happiness: Kant argues that happiness is not morally good unless the person is "worthy" of it. An "impartial spectator" would not find satisfaction in seeing an unjust or cruel person being happy. Thus, goodwill is the condition for being worthy of happiness.
The Independence of the Goodwill from Results
Core Claim: A goodwill is good in itself, not because of what it accomplishes or its "serviceability."
Misunderstanding 1: Consequences are Irrelevant:
Some might think Kant says we shouldn't care about the consequences of actions.
Correction: Since the will is practical reason, a good will involves good reasoning. Good reasoning must include the consideration of predictable and likely consequences.
Example: Watering a neighbor's plant is good, but doing so while ignoring a live electrical cable that could cause a fire is bad reasoning, and therefore not an act of a good will.
Misunderstanding 2: Good Thoughts are Sufficient:
Some might think having "nice thoughts" is enough.
Correction: The will is practical; it is directed toward action. A "mere wish" (wanting something without steps to achieve it) is not a will. Willing involves the "mobilization of all means insofar as they are in our control."
The "Jewel" Metaphor: If a person reasons well and attempts to act with the best information available, but is thwarted by the "peculiar disfavor of fate" (e.g., a tree blocking the road when someone is early for a meeting), the goodwill still "shines like a jewel."
The Vocation of Reason
The Purpose of the Organ: Kant assumes the teleological principle that every faculty and organ in a living (organized) being is the one "most suitable and appropriate" for its end.
Critique of Reason for Happiness:
If nature's end for humans were happiness (satisfying desires), instinct would have been a far more efficient tool than reason.
"Cultivated reason" often leads to less happiness and more frustration, causing many to envy those who follow simple instinct.
The True Function of Practical Reason:
Since reason is a poor tool for achieving happiness, its true "vocation" must be to produce something that is good in itself: a goodwill.
Reason's aim is not to satisfy inclinations but to produce an unconditionally good will.
Questions & Discussion
Question on Courage: A student asked how courage could be bad, suggesting that someone killing innocents in an unjust war is actually "cowardly" for not standing up for their morals.
Response: The student is applying Aristotle's philosophical definition. Kant is addressing the "common" understanding of courage as mere "boldness" or the ability to resist fear/not feel fear. In the common sense, a bold but evil person is considered courageous but not good.
Question on Unforeseen Results: A student asked if someone in a hallucitatory state who intends good but causes harm would still have a good will.
Response: Kant would say yes. If the will is "unconditionally good," its value cannot depend on variables outside its control. If goodwill depended on external outcomes for its worth, it would be "conditional."
Question on Cultural/Learned Morality: A student asked if goodwill is taught and varies across cultures, challenging the idea of it being without limitation.
Response: Relevant information (culture, social facts) is part of the "input" for practical reasoning. However, Kant believes there are universal "standards" of reasoning—similar to logical rules—that apply regardless of the specific information used. These universal standards define "good reasoning."
Discussion on the Hierarchy of Desires: A student noted that Hume's view leads to a hierarchy where reason is just a slave, but there might be a "conscience" or higher reasoning.
Response: Kant disagrees with the idea of a simple hierarchy. He believes reason can set its own ends that are "categorically different" and "absolutely better" than those set by emotions or passions. This makes reason's end incomparable to any other goal.
