Opinion involves belief (for without belief in what we opine we cannot have an opinion), and in the brutes though we often find imagination we never find belief.
All the manifested world of things and beings are projected by imagination upon the substratum which is the Eternal All-pervading Vishnu, whose nature is Existence-Intelligence; just as the different ornaments are all made out of the same gold.
The imagination ... that reconciling and mediatory power, which incorporating the reason in images of the sense and organizing (as it were) the flux of the senses by the permanence and self-circling energies of the reason, gives birth to a system of symbols, harmonious in themselves, and consubstantial with the truths of which they are the conductors.

What acts as a far more effective circumstance for generating compassion and what, in fact, rouses us from our comfortable meditation seat is actually seeing or hearing others - encountering others directly, not just conceptually in our imagination.
We wish to find the truth, no matter where it lies. But to find the truth we need imagination and skepticism both. We will not be afraid to speculate, but we will be careful to distinguish speculation from fact.

You can be a thorough-going Neo-Darwinian without imagination, metaphysics, poetry, conscience, or decency. For 'Natural Selection' has no moral significance: it deals with that part of evolution which has no purpose, no intelligence, and might more appropriately be called accidental selection, or better still, Unnatural Selection, since nothing is more unnatural than an accident. If it could be proved that the whole universe had been produced by such Selection, only fools and rascals could bear to live.
'Mind and matter,' said the lady in the wig, 'glide swift into the vortex if immensity. Howls the sublime, and softly sleeps the calm Ideal, in the whispering chambers of Imagination.'
