Step-by-step explanation:
German philosopher Immanuel Kant proposed a transcendental idealist perspective on the existence of intersubjective reality. According to Kant, our perception of objects and reality is shaped by the structure of our minds. He argued that humans can only know objects as they appear to us, not as they are in themselves. Kant believed that intersubjective reality arises from the shared structure of human consciousness and the way we perceive and interpret the world.
