“So, human beings complain that the world is ill-made, do they? But ill-made for whom? For Man, who, in the immense design of the Universe is no more than an unimportant mould! The probability is that everything in this world which we think is botched or erroneous has its reasons at a totally different level of existence. The mould endures, no doubt, a small amount of suffering, but somewhere there are giants who, huge in stature as in mind, live in a state of semi-divinity. This is Voltaire's answer to the problem of evil. It is not very satisfactory because the mould need never have been created, and, in the eyes of God, it may well be that mere size is of no importance.”

Variant: Mind is the Master Power that molds and makes, And we are mind. And ever more we take the tool of thought, and shaping what we will, bring forth a thousand joys, or a thousand ills. We think in secret, and it comes to pass, environment, is but our looking glass.

That death caught people rather unawares. Do not discount the possibility that in a few years time someone may be able to write at least equally convincingly of the strange and rapid revival of liberal social democratic Britain.
