"A few observation and much reasoning lead to error; many observations and a little reasoning to truth"

This quote by Alexis Carrel recommends that when it pertains to finding fact, it is important to have a balance between observation and thinking. Too few observations and excessive reasoning can lead to error, while many observations and a little thinking can lead to reality. This suggests that observation is just as crucial as thinking when it pertains to finding reality. Carrel is suggesting that observation is the structure of truth, and thinking is the tool used to analyze the observations. Without observation, thinking is simply speculation. On the other hand, without reasoning, observations are just realities without any significance. For that reason, it is very important to have a balance in between observation and thinking in order to find reality.
