Abstract ideas require concrete references to avoid becoming hollow. Likewise, valuable intuitions need a solid theoretical foundation to avoid being misled. Immanuel Kant, often viewed as the father of modernity, critiques the overestimation of human reason by acknowledging its limitations. While we can comprehend certain realities, known as phenomena, there are aspects of existence, referred to as noumena or "things-in-themselves," that are beyond our understanding. These include concepts like divine matters and heaven, which remain perpetually inaccessible.
Ultimately, we need to strike a balance between logical reasoning and practical experience to make sound decisions.
In fact, Kant-like thinkers existed long before him. Confucius and Laozi from China, in the 5th to 6th centuries BCE, expressed similar ideas about knowledge and its limitations.
