Philosophy

I've been reading about philosophy and I got annoyed by these two examples I read on wikipedia:

Kant claimed that dialectic method was sterile because it led to contradictory conclusions? The dialectic method as it is was used by the famous philosophers itself was not the cause of the contradictions. The cause must have been undetected errors in the logic of the arguments presented within that method. Just like our more modern scientific method for arriving at actual physical knowledge doesn't work if you don't reason well within each step.

I read that in Hegel's "The Logic", Hegel talks about how quality and quantity are related, using the temperature of water was a really bad example. Clearly the fact that the water changes from liquid to steam at a 100 degrees Celsius does not stem from the relationship between quality and quantity, it stems from the nature of water. Would he have come to a different conclusion if he had instead used the number of molecules of water as the quantity to change instead of temperature?

Reason is a tool, but you get out of it what you put into it... if your facts or premises are faulty, or if your connections are faulty because you're not diligent at checking for contradictions or gaps, you will arrive at faulty conclusions. Reason is just a process. To use reason reliably we need to take careful steps and check each other's work critically.

Reason is a team sport!
