British philosophers, John Locke and David Hume, are considered empiricists. This is because they based their philosophies on natural science. Both philosophers contributed to the theory of knowledge with Locke coming up with sensations and reflections and Hume coming up with impressions and ideas as the cornerstones of their theories of knowledge. Their theories aim to show us that everything we understand is by virtue of its connection with experience. Experience, therefore is the source of knowledge for these philosophers.
This paper looks into empiricism both as a source and method of knowledge. The approach taken is by mirroring John Locke’s theory of knowledge with that of David Hume, identifying similarities, influence of Locke on Hume, the differences between them and a critique on the credibility of empiricism, as one of the sources and methods of knowledge.
The conclusion arrived at is that empiricist ideas can explain the physical world and what we know of it but there remains rationally derived knowledge. On this account, both empiricism and rationalism are credible sources and methods of knowledge.

Objectives and Topics
This work aims to provide a critical comparison between the epistemological theories of John Locke and David Hume. By analyzing their shared empiricist foundations—specifically the roles of sensation, reflection, impressions, and ideas—the author seeks to evaluate the credibility of empiricism as a primary source of knowledge and contrast it with rationalist perspectives.
- Comparison of Locke’s concepts of sensation and reflection with Hume’s impressions and ideas.
- Examination of the influence of Locke’s empiricist framework on Hume’s philosophical development.
- Critique of empiricism’s limitations in establishing eternal and immutable truths.
- Evaluation of the "representational" nature of knowledge and its tendency toward skepticism.
- Discussion on the necessity of integrating rational deduction alongside sensory observation.
Excerpt from the Book
JOHN LOCKE'S PHILOSOPHY AND HIS THEORY OF KNOWLEDGE.
John Locke (1632-1704) in his book Essay Concerning Human Understanding set out his task as ‘to examine our Abilities, and see what Objects our Understandings are, or are not fitted to deal with’. To Grayling, A.C, this implies an inquiry into ‘the Original, Certainty, and Extent of humane Knowledge, together with the Grounds and Degrees of Belief, Opinion and Assent’. Grayling notes that Locke’s strategy was to agree with rationalism that certainty is a property of intuitive and demonstrative knowledge, then to assert the right of what Locke refers to as ‘sensitive knowledge’. That is, knowledge from the senses should be taken seriously.
To Scruton, R, Locke wishes to show that everything that we understand (every idea) we understand in virtue of its connection with experience. That is, the content of every idea we have is revealed by tracing it back to experience. Here, we already can see Locke proposing, an empiricist theory of understanding. Put simply, all our ideas come from experience.
Francks goes on to note that to Locke, when a child is born it knows nothing, its compared to a blank sheet of paper, waiting for life to write words on it, waiting to be ‘furnished’ with ‘ideas’. What do we mean by this? Here, Locke means that our minds get furnished by ‘experience’. That is, I learn what is warm by being warm; I learn what is pain by feeling it.
Summary of Chapters
Introduction: This chapter defines the core concepts of empiricism, including sensation, reflection, and impressions, while establishing the scope of the comparative analysis between Locke and Hume.
John Locke's Philosophy and His Theory of Knowledge.: This section examines Locke’s assertion that all ideas originate from sensory experience and explains his classification of knowledge into intuitive, demonstrative, and sensitive forms.
David Hume's Philosophy and His Theory of Knowledge.: This chapter analyzes Hume's refinement of empiricism through the Newtonian method, focusing on the distinction between forceful impressions and faint ideas as the basis of human thought.

Frequently Asked Questions
What is the primary focus of this academic paper?
The paper is an epistemological study that mirrors the theories of John Locke and David Hume to evaluate their contributions to empiricism.
What are the central themes discussed in the work?
The core themes include the source and nature of knowledge, the distinction between simple and complex ideas, and the critique of empiricism versus rationalist deductive systems.
What is the main research objective of the author?
The objective is to identify the similarities and differences between Locke and Hume, analyze the influence of the former on the latter, and critique the overall credibility of empiricism.
Which scientific method is utilized in this epistemological inquiry?
The paper emphasizes an observation-based approach, noting that Hume specifically employed a Newtonian method to discover the laws governing human nature and mental operations.
What topics are covered in the main body?
The main body provides detailed definitions of empiricist terminology (sensation, reflection, impressions) and a critical exposition of how both philosophers attempt to trace all understanding back to sensory experience.
Which keywords best characterize this research?
Key terms include empiricism, epistemology, sensation, reflection, impressions, ideas, perception, and sense-data.
Why does Locke categorize knowledge into three distinct degrees?
Locke utilizes intuitive, demonstrative, and sensitive knowledge to account for different levels of certainty regarding our own existence, the existence of God, and external objects.
How does Hume distinguish between impressions and ideas?
Hume differentiates them based on the degree of vivacity or forcefulness; impressions are vivid sensory experiences, while ideas are the faint mental "copies" that remain after the original sensation has passed.
What criticism does the author level against empiricism?
The author argues that experience alone cannot lead to eternal and immutable truths, suggesting that rational deduction and other forms of reasoning are necessary to supplement empirical data.
How does the concept of "representationalism" lead to skepticism?
The author notes that if our ideas are merely representations or "pictures" of reality, it becomes difficult to verify their accuracy, which opens the door to philosophical skepticism regarding the external world.
