The Science of Morality: Sam Harris' 'The Moral Landscape' Explored

Introduction

Sam Harris' book 'The Moral Landscape: How Science Can Determine Human Values' presents a thought-provoking and controversial thesis on the intersection of science, morality, and human well-being. Published in 2010, this 264-page work draws from Harris' background as a neuroscientist and philosopher to argue that science can and should play a central role in determining moral values.

The Moral Landscape Defined

Harris introduces the concept of a "moral landscape" as a way to visualize and understand moral values:

• The landscape metaphor represents the spectrum of possible states of well-being for conscious creatures
• Peaks on this landscape correspond to the heights of human flourishing and well-being
• Valleys represent the depths of suffering and moral failure
• Movement across this landscape is possible, though the exact path may not always be clear

This framework allows Harris to discuss morality in terms that can be potentially measured and studied scientifically, rather than relying solely on philosophical or religious arguments.

Key Arguments and Concepts

Well-being as the Foundation of Morality

Harris posits that the overall well-being of conscious creatures should be the fundamental basis for moral considerations. He argues that:

• Maximizing the well-being of the greatest number of individuals should be the goal of moral behavior
• A "perfect moral society" would treat all individuals equally, regardless of their background or identity
• Cooperation is essential for morality, while deception and lying are antithetical to moral progress

The Health Analogy

To illustrate his point about the scientific study of morality, Harris draws a parallel with human health:

• We can objectively identify states of poor health (e.g., cancer, diabetes)
• While we may not be able to define "perfect health" precisely, we can study and measure factors that contribute to good health
• Similarly, we can identify clear cases of moral wrongdoing and study factors that contribute to moral behavior and well-being

Science and Moral Truth

Harris argues that science can provide answers to moral questions, even if it cannot always give us perfect certainty:

• There are objectively right and wrong answers to moral questions
• Scientific methods, including neuroscience and behavioral studies, can help us understand and evaluate moral claims
• While we may not always be able to determine the exact moral truth in every situation, science can guide us towards better moral decisions

Evolution and Morality

Harris challenges the idea that evolutionary explanations are sufficient to account for human morality:

• Evolutionary beneficial behaviors (e.g., consuming excess calories, infidelity) are not necessarily morally good in modern contexts
• Humans have developed complex social and cognitive abilities that allow us to transcend purely evolutionary drives
• Moral reasoning should consider long-term well-being rather than just short-term evolutionary advantages

Critique of Moral Relativism

Harris strongly opposes moral relativism, the idea that moral truths are culturally dependent:

• Some moral positions are objectively wrong (e.g., extremist ideologies that promote violence)
• Cultural differences do not negate the existence of universal moral truths
• Science can help us identify and evaluate moral claims across cultures

Belief and Neuroscience

Harris explores the role of belief in morality and how it can be studied scientifically:

• Belief bridges the gap between facts and feelings
• While specific beliefs may not be genetically coded, the capacity for belief and complex thought can be studied neurologically
• fMRI scans can potentially differentiate between truthful and deceptive states, opening up new avenues for understanding moral behavior

Religion and Morality

As an atheist, Harris critically examines the relationship between religion and morality:

• He argues that there is a fundamental difficulty in reconciling science and faith
• Harris notes that less religious countries often score better on various measures of societal health and well-being
• He challenges the idea that morality must come from God or religious teachings
• Harris argues that deriving morality solely from religious texts often requires cherry-picking and ignoring problematic aspects

The Golden Rule

Harris acknowledges the value of the Golden Rule (treat others as you would want to be treated) but argues that it is not unique to religious teachings:

• The Golden Rule can be derived from rational consideration of human well-being
• It is a principle that we apply to religious texts, rather than one that originates from them

Criticisms of Both Liberal and Conservative Approaches

Harris doesn't shy away from criticizing both ends of the political spectrum:

• He argues that extreme liberal tolerance can be counterproductive, especially when it leads to accepting harmful practices in the name of cultural relativism
• Conservative intolerance and rigid adherence to religious doctrines can also hinder moral progress
• Harris advocates for a balanced approach that uses scientific evidence to evaluate moral claims

The Future of Happiness

Despite the heavy subject matter, Harris ends on a hopeful note:

• He believes that science and philosophy can work together to improve human well-being
• While not acknowledging the existence of a soul or consciousness beyond the physical brain, Harris leaves room for future scientific discoveries that might change our understanding of these concepts

Strengths and Weaknesses of Harris' Argument

Strengths

• Extensive use of scientific sources and studies to support claims
• Addresses potential criticisms and counterarguments directly
• Offers a fresh perspective on the relationship between science and morality

Weaknesses

• Many of Harris' proposals remain theoretical and untested
• Some critics argue that his fundamental premises are philosophical rather than scientific
• The book can be overwhelming in its density of information and references

Critical Reception

Harris' work has received both praise and criticism from various quarters:

Positive Reception

• Richard Dawkins praised Harris' critique of religious morality
• Some academics have noted the consistency of Harris' approach with behavioral analysis
• Others have appreciated his challenge to moral relativism and cultural quietism

Criticisms

• Some find the book "bullheaded" despite addressing an interesting topic
• Critics argue that Harris' fundamental premises are philosophical rather than scientific
• Religious thinkers like William Lane Craig argue that Harris fails to provide a sound foundation for objective moral values without God

Conclusion

'The Moral Landscape' is a challenging and thought-provoking work that attempts to bridge the gap between science and morality. While it may not provide all the answers, it certainly raises important questions about how we determine right and wrong in the modern world.

Harris' central thesis - that science can and should inform our moral decisions - is likely to remain controversial. However, his call for a more rigorous, evidence-based approach to ethics is worth considering, even for those who may disagree with his specific conclusions.

Ultimately, 'The Moral Landscape' serves as a starting point for further discussion and research into the scientific basis of morality. It challenges readers to think critically about their own moral assumptions and consider how scientific knowledge might inform ethical decision-making.

While the book may be too dense for casual readers, it offers valuable insights for those deeply interested in the intersection of science, philosophy, and ethics. As we continue to grapple with complex moral issues in an increasingly interconnected world, the ideas presented in 'The Moral Landscape' are likely to remain relevant and worthy of debate for years to come.
