This common statement used by anyone intending to “philosophise” or rather avoid further “philosophising” intrigued me for the first time. Probably as a matter of constructing a robust come-back.
My view is…I doubt life is an illusion. The definition of it clearly shows that is nothing but a norm/ condition in order for one to distinguish organisms from inorganic objects and dead organisms, being manifested by growth through metabolism , reproduction, etc. By suggesting that it is an illusion (illusion is something that deceives by producing a false or misleading impression of reality), you basically claim that there is no difference between a dead organism, an alive organism and an inorganic object.
Imagination is the formation of a mental image of something that is neither perceived as real nor present to the senses. Therefore, it cannot be mixed with reality as they are opposite by definition. Reality is claimed to be the quality or state of being actual or true. Truth is extremely relative as a notion.
Reality is…something. and every other word that could contradict its existence has somehow a link to it, which makes difficult to break it down to what it is exactly. Is this another game of words? Is this a sign that every single bit of this world ensures the existence uncertainty as well as a warning to prevent anyone from trying to go into it since there would be no possible way of describing exactly what they are looking for, not even proposing it, therefore not even being able to have the starting point for the search which would be the ‘keyphrase’. Scary.
