Some problems of philosophy

What are ideas and what are things? And how is the connection between them? What do we mean when we say truth? Is there a common substance from which all facts are made? How was there a world? And was it possible that there was no world? What is the true nature of objective truth? What links all things in one world? Is unity or multiplicity more essential? Do all things have a single origin? Or many origins? Is everything possible, or are some things, like our will, free? Is the world infinite or finite in its entirety? Are its parts connected or is there emptiness? What is God? How do mind and body unite? And does each affect the other? How does one thing influence another? How does something change or grow from something else? Are space and time entities or what? And in knowledge: how does the subject penetrate the mind? Or how does the mind penetrate the subject? And our knowledge is achieved through general ideas, so are these ideas also real? Or are only the particular things the real ones? And what do we mean by the word thing? And "principles of reason," are they innate or acquired? Do beauty and goodness belong only to personal opinion? Or do they have objective legitimacy? And if so, what does this objective legitimacy mean? Number of pages: 200 Year of publication: 2021 Publisher: Arab Pens for Publishing and Distribution
