0:04 → 0:12
The primary aim of critical thinking and science in general is to try and derive what we may call objective knowledge.
0:12 → 0:19
Critical thinking is not philosophy where we might be searching for some form of absolute truth with a capital T.
0:19 → 0:23
Critical Thinking and science are much more practical in their nature.
0:23 → 0:29
Rather than aiming for an absolute truth they're looking for knowledge that works.
0:29 → 0:37
That is to say knowledge that remains relevant under scrutiny from many different perspectives and within many different frames of reference.
0:37 → 0:46
This is objective knowledge in that it is not contingent upon a specific subject or context, but is relevant to many different contexts.
0:47 → 0:50
This objective knowledge we may call logic.
0:50 → 0:55
Things in our world work in a particular way because of the logic governing them.
0:55 → 0:59
When we understand that logic we understand how they work.
0:59 → 1:02
And this is a very practical measure of knowledge.
1:02 → 1:11
With science and critical thinking, we're trying to develop standards and methods for deriving this objective knowledge about the world around us.
1:11 → 1:16
And we can call this objective knowledge "logic", where logic is simply the way things work.
1:16 → 1:20
Thus at the heart of critical thinking is this idea of logic.
1:20 → 1:27
And in this section, we'll be exploring this very big and fundamental idea in a number of different perspectives.
