Ludwig Wittgenstein - from On Certainty:
"467. I am sitting with a philosopher in the garden; he says again and again "I know that that's a tree", pointing to a tree that is near us. Someone else arrives and hears this, and I tell him: "This fellow isn't insane. We are only doing philosophy."
Behold the mighty 813 pentode, originally designed for rf (radio) transmitter applications. However - when hauled into service for af (audio) applications, these pentodes produce the sweet, powerful and cosmic sonics:
Substituting "pentodes" for "experiments".
Suppose that - in my mind, I imagine that I apply 30K Volts DC to the anode of a thought 813 pentode and set the idle bias to .500 Amps. Will my thought pentode explode - independently of my thinking that it explodes?
Should I apply the exact amount of voltage to and push the same amount of current through an existing 813 pentode - barring a breakdown in the laws of physics, the existing tube will explode (or melt) independently of my thinking that it explodes.
Existing (non-imaginary) 813 pentodes have a max voltage rating of 2500 Volts DC and a max wattage rating of 125 Watts. Applying 30K Volts DC to and pushing .500 Amps through an existing 813 would exceed the max wattage rating by around 120 fold, frying it. Thought pentodes ain't existing pentodes.
One can think about experiments and pentodes, but one cannot bring either an experiment or a pentode into existence by thinking. Neither experiments nor pentodes "exist" "in the form of thought". An experiment or a pentode must appear in more than human thought for it to exist in reality. Events occur under mind-independent conditions - which only reality provides. Reality is the sole truth-condition generator. Human minds cannot produce the external circumstances - under which any event occurs.
When you prefix the occult-word "thought" to another word - say - a thing or a human activity, it does not follow that the newly conjoined phrase picks-out any state of affairs, existing in the world. For example:
