Philosophical question: What can I know?
Here's the response:
That question—**"What can I know?"**—is one of the most fundamental in philosophy. It's at the heart of **epistemology**, the study of knowledge. Let’s explore it from a few key philosophical angles:
---
### 1. **Descartes and Radical Doubt**
René Descartes began his search for certainty by doubting everything he could:
> "I think, therefore I am" (*Cogito, ergo sum*)
He concluded that the only thing he could not doubt was **his own existence as a thinking being**. Everything else—sensory experiences, external reality, even mathematics—could be called into question.
So from this view, you can know:
* That you are **thinking**
* That **you exist** (at least as a mind)
---
### 2. **Empiricism (Locke, Hume, etc.)**
Empiricists argue that knowledge comes from **sense experience**. You know things because you perceive them through your senses.
But this leads to skepticism about:
* Whether your senses **reliably** reflect reality
* Whether there's anything **beyond your perceptions**
So, empirically, you can know:
* Your **experiences**
* Maybe some regularities in those experiences (e.g., fire is hot)
---
### 3. **Kant’s Synthesis**
Immanuel Kant tried to bridge rationalism and empiricism. He argued:
* We never know things **in themselves** (*noumena*)
* We only know things **as they appear to us** (*phenomena*), structured by our minds
So what can you know?
* The **structure of experience** (space, time, causality)
* Not reality in itself, but how it appears **to human minds**
---
### 4. **Contemporary Epistemology**
Modern philosophers often break down knowledge as:
> **Justified True Belief (JTB)** — though this was challenged by the **Gettier problem**
Now, knowledge is seen as:
* **Belief**
* That is **true**
* And **justified** (in some defensible way)
* Possibly requiring **no luck** or **reliable formation**
So: You can know what’s **justifiably believed and true**—but drawing the line is tricky.

### 5. **Pragmatism (James, Dewey, Rorty)**
Knowledge is what **works**—what helps you navigate the world effectively. It doesn't require certainty.
So you know:
* What is **useful** in practice
* What’s **coherent** with the rest of what you believe
---
### Summary: *What Can You Know?*
* **You exist** (as a thinker)
* **You experience** things
* Some beliefs may be **justified and true**
* But many things remain **uncertain**, and **context**, **coherence**, or **pragmatic usefulness** might matter more than absolute certainty.
