This is simply an appeal to emotion. You have no idea how Ruse views those he's had relationships with do you? Or are you contending that anyone who has sex with more than one person necessarily treats others as disposable by definition?
BTW that little nugget of yours' Purity of heart and wisdom goes hand in hand' is a pretty wild assertion. Want to tell me what this 'purity of heart' means, and how wisdom is not possible without it?
It means that it's okay to have sex with lots of people, so long as you don't enjoy it.
Well, it wasn't "purity of body", so you tell me...
It's a logical argument. A person who, unprompted, publicly boasts about serial fornication is most likely someone who regards fornication lightly. Most men who sleep around do so for pleasure, and regard their partners as conquests. I have no reason to suspect otherwise with Mr. Ruse.
Therefore, his ability to dispassionatley judge between the theories of materialistic evolution and intelligent design as explanations for human origins is unlikely, since affirmation of ID entails acknowledgement of a Designer of both physical and moral laws, the latter of which would be repugnant to a whore.

And raises his sins in an article putatively dealing with biological science? Yes.

It's empirically demonstrable. Good people make good philosohers and evil people make bad philosophers. See Marx, Nietszche, Satre, etc. OTOH, the greatest philosophers, Socrates, Aristotle, St. Thomas, St. Bonaventure and St. Albert the Great, were also virtuous people. The books "Intellectuals" and "Architects of the Culture of Death" present an overwhelming case.
Want to tell me what this 'purity of heart' means,
Good. Virtuous.
and how wisdom is not possible without it?
Evil people regard sin as "good" for them. This is false. But from this false assumption they attempt to build a philosophical system that won't contradict their sinful practices. Philosophy based on lies can go in any direction, but never an ultimately good or true direction.
