I had the delight of reading Language Truth and Logic by Alfred Jules Ayer to come to the insight that the language we use is direct reflection on how we think. If you truly want to understand someone you only need to listen and sometimes ask questions. We can assess the quality of a persons thinking, their knowledge base and their use of logic in reasoning.
Likewise, the book seeks to discredit in some ways intuition and focuses more on an empirical method of understanding. A often focuses on a priori understanding as not worthy of philosophy and seeks more to make a case for direct experience through our senses.
The book definately fits within our current perception of science and how ways of knowing can be measured and understood. However, one may make the argument that there are periods before our ability to measure a concept that we "know" something and are forming an understanding of it.
This is drawn from experience and the ability of our brains to understand the world around them. It would be pretty difficult to have a scientific breakthrough if all things need to be measured right away. Instead I would say that knowledge and experience can lead to leaps in mental creativity that can later be measured for accuracy. As a discussion of language and logic the book is pretty good but a little boring to the average reader.
