Why wanting something is not the same as intending to do it

In short: You can desire a sunny day, but you cannot intend one. While we often use these words interchangeably, philosophy reveals a sharp distinction: intentions require a practical commitment to an action plan. Understanding this gap explains why we often fail to act on our strongest desires.

Philosophers distinguish intentions from mere desires or beliefs by looking at 'commitment.' An intention is a mental state where an agent commits to a specific action plan. While a desire might evaluate an outcome as 'good in some sense,' an intention treats a course of action as 'good all things considered.' This means that while you might desire to help the poor, you only intend to do so once you have settled on a specific plan and committed to its execution. The 'belief–desire theory' is the traditional framework for this, suggesting that an intention is simply the combination of a desire to act and a belief that you will. However, this is frequently criticized because beliefs and desires lack the 'settledness' required for action. For instance, a person might desire to retaliate against an insult and believe they will do so based on past behavior, yet still lack a true intention because they haven't fully decided to act. Conversely, one can have an intention without a firm belief in success, such as intending to complete a task despite a history of previous failures. Furthermore, intentions are categorized by their timing. 'Prospective intentions' are plans for the future, while 'immediate intentions' guide behavior as it happens. They also possess 'conditions of satisfaction,' meaning they are either successful or unsuccessful based on whether the resulting behavior meets the goal. Because success often depends on external factors beyond an agent's control, an intention can be 'unsuccessful' even if the agent made a sincere commitment to the plan.
