Isn’t this anachronistic?

Harking back to an age of experts?

Isn’t it philosophically naïve?

Especially when we considerpolitically controversial topics.

What is a fact, anyway?
![Page 11: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/11.jpg)
Don’t ask what a fact is…

…ask what a fact does.

Or better, what you do whenyou call something a fact.

It’s a fact that the climate is changing
and that sea levels are rising.

It’s a fact that most people in Australia have a higher

Giving Reasons

Philosophically naïve?

No

Isn’t this anachronistic?

No

Looking back to an age of experts?
![Page 31: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/31.jpg)
No, but…

You show that something is a fact by giving your reasons.
![Page 33: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/33.jpg)
We move beyond “he said / she said” journalism.
![Page 34: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/34.jpg)

What about when Fact-Checking sites disagree?
![Page 36: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/36.jpg)

What about areas of moral disagreement?
![Page 40: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/40.jpg)
Providing reasons can help, even when it doesn’t lead to agreement.
![Page 41: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/41.jpg)
It maps out the field of options.
![Page 42: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/42.jpg)
It helps us understand each other.
![Page 43: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/43.jpg)
We keep each other (and ourselves) honest.
![Page 44: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/44.jpg)
We learn more of what a claim really involves.
![Page 45: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/45.jpg)
Sometimes, it can convince.
![Page 46: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/46.jpg)
Where can we go from here?
![Page 47: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/47.jpg)
Fact-Checking sites are a start.
![Page 48: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/48.jpg)
Support them, and supportquality journalism
over “he said / she said” substitutes.
![Page 49: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/49.jpg)
Inculcate a culture of valuing reasons.
![Page 50: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/50.jpg)
The more you are exposed to good reasoning, the more
you’ll recognise it, and be able to produce great reasoning of your own.
![Page 51: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/51.jpg)
Be prepared to give your reasons,and be curious about the
reasons of others.
![Page 52: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/52.jpg)
Don’t expect to come to agreement.
![Page 53: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/53.jpg)
But be prepared to find some common ground.
![Page 54: Logic and Rationality; Disagreement and Evidence - Greg Restall](https://reader034.fdocuments.net/reader034/viewer/2022042521/5565a736d8b42a0a768b542e/html5/thumbnails/54.jpg)
