This quote by Voltaire suggests that humans, despite our advanced intelligence and capabilities, often experience more misery than animals. Animals, such as dogs, monkeys, and parrots, are thought to live in the moment without worrying about the past or the future. They don’t dwell on regrets, fear, or anxiety, which are common sources of human misery.

Voltaire might be implying that our advanced cognition, which allows us to contemplate the past, present, and future, can also lead to greater suffering. We have the ability to worry about things that may never happen, regret past actions, or feel anxious about our place in the world. Animals, on the other hand, live in the present, focused on basic needs like food, safety, and social interaction. This simplicity, according to Voltaire, makes them less miserable than humans.

In today’s world, this idea can be applied in the context of mindfulness and mental health. Many modern stressors come from overthinking, worrying about the future, or dwelling on the past. Mindfulness, or the practice of being fully present and engaged in the current moment, can help reduce these stressors. Just as dogs, monkeys, and parrots live in the moment, humans can also strive to be more present, reducing unnecessary worries and anxieties.

In terms of personal development, this quote can serve as a reminder to simplify life and focus on what truly matters. It suggests that happiness might be found not in complexity, but in simplicity. This could mean spending more time in nature, focusing on basic needs and pleasures, and spending less time worrying about things beyond our control.

Overall, Voltaire’s quote serves as a reminder of the importance of living in the present and focusing on the simple pleasures of life to reduce misery and increase happiness.
