Limitations of Scientific Explanations

The speaker expresses skepticism towards the idea that all philosophical questions about the nature and universe can be resolved through naturalistic means. They argue that despite scientific advancements, there are still open questions that may never be fully understood through science alone. They criticize the idea that providing scientific explanations for phenomena fully explains them, citing the example of gravity. The speaker believes that having a scientific theory to explain a phenomenon does not equate to understanding the 'why' behind it, as some questions may remain unanswered even with scientific progress. They highlight the distinction between explaining the mechanism of events like the Big Bang and understanding the fundamental reasons behind them, indicating that some aspects of the universe may always defy complete scientific explanation.
