" For psychological purposes the most important differences in conation are those in virtue of which the object is revealed as sensed or perceived or imaged or remembered or thought. "
- Samuel Alexander

In simple terms, Samuel Alexander's statement highlights that our mental activities are categorized into different types based on how we perceive or think about an object. These categories include sensing something directly through our senses, perceiving it cognitively, imagining it, remembering it from the past, and thinking abstractly about it.

Exploring beyond its literal meaning, this quote delves into the complex nature of human cognition and consciousness. Alexander is emphasizing that each type of mental engagement with an object—whether through direct sensory experience or more abstract cognitive processes like thought—provides a unique perspective on reality. This understanding allows us to appreciate how our perception of objects can vary widely based on whether we are sensing them, remembering them, imagining them, perceiving them cognitively, or thinking about them conceptually. Each mode of engagement enriches our overall comprehension and interaction with the world around us.

Samuel Alexander was a British philosopher known for his work in metaphysics and the philosophy of space, time, and matter. He contributed significantly to the development of neo-Hegelian thought and idealism, exploring how reality is perceived and experienced through different cognitive functions.
