"Intense feeling too often obscures the truth"

This quote by Harry S. Truman recommends that strong emotions can frequently cloud our judgement and prevent us from seeing the reality. Truman is recommending that when we are feeling intense feelings, such as anger, fear, or sadness, it can be tough to think clearly and objectively. We may be so focused on our own sensations that we are unable to see the facts and truth of the situation. This can lead to us making decisions that are not based on the reality, but rather on our own emotional state. Truman is cautioning us to be aware of our emotions and to take a step back to evaluate the circumstance objectively before making any choices.
