formulæ

Formulá is a term that has been used in various contexts throughout history, but it is most notably associated with the ancient Greek philosopher Plato. In Plato's dialogues, particularly the "Theaetetus," the term "formulá" (or "eidos") refers to the eternal, unchanging forms or ideas that exist independently of the physical world. These forms are the essence of things, and they are the basis of Plato's theory of knowledge and reality.

Plato believed that the world we perceive through our senses is a mere shadow or reflection of the true reality, which is composed of these eternal forms. For example, the form of beauty is a perfect, unchanging idea that exists independently of any particular beautiful object. When we perceive beauty in the world, we are perceiving an imperfect reflection of this eternal form.

The concept of formulá is central to Plato's philosophy and has had a significant influence on Western thought. It has been interpreted and developed by many philosophers over the centuries, and it continues to be a subject of debate and discussion in academic and philosophical circles today.
