What is wisdom? Introduction: Wisdom is generally regarded as a certain body of knowledge that has both a practical and theoretical aspect. This knowledge inevitably leads the person who possesses it to live a good life. This is because a wise person is someone who knows the right things, knows how to put them into practice rationally and manages to do so and therefore live a good life. Thesis: I argue that wisdom is a blend of practical knowledge and abstract knowledge in which a person is capable and able to apply these ideas in a rational way that results in a good life. Argument: To be truly wise it seems clear that a person must know the universe and one's place in it. Therefore such in-depth knowledge is necessary. But they must also have in-depth knowledge of their own lives and therefore must be well-versed in the correct way to apply this knowledge and therefore know how to best live. Such a person's knowledge will also make clear to him the intrinsic value of living well, and he must therefore desire it as well as know how to obtain it (Hursthouse 12). Someone who does not live well and therefore virtuously certainly cannot be wise. As long as we don't assume that wisdom must be attainable by all people, there is no problem. However, it should also be noted that the condition is that a wise person has extensive theoretical knowledge. This says nothing about false beliefs. An ancient person, if truly wise, will have investigated the world to the extent that it must surely be true that he has a great deal of true beliefs. The fact that alongside those true beliefs they also have false ones due to the primitive time in which they live does not deny the extensive theoretical knowledge they still possess.
